I'll (hopefully) once and for all address this by saying things ive outright said or alluded to already...the member seemed to be veering off into territory i have personally 0 time for, blocking everything from the viewpoint of "must stop all background app chatter" (using some of his own terms here).
As you know, because ive shared it in private, i have my own module for blocking ad/tracking receivers, but its very basic, so im not opposed to seeking to increase privacy, save CPU cycles and battery, but some people take it to levels i consider extreme and motivated by thought processes i find also bordering on extreme.... theres a lot of holdover of practices used in early Android that we all see about the place that really has no real place in recent Android...you still see people with half mile long build.prop hacks, despite most of those being removed in code years ago. Then theres outright horse output, like other day i still saw people asserting that copying VoLTE (Qualcomm) onto Exynos based devices would somehow magically enable VoLTE for people. It may seem off-brand, but where possible i like to attempt to dial back the crazy....
p.s. i found in my switch back to Pixel the other night in their threads this module which is a bit smarter than mine as it allows you to specify user or system app (something which i never thought to add to mine)
Attached is a (simple) Magisk module which allows you to disable: - app measurement - app analytics - app firebase tracking - app crashlytics In short, each APK (system app or user app) may have background services to do all sorts of tracking...

So im not opposed to the topic of blocking ad receivers/trackers, again as i said to the member in question, and to all in general thats a personal choice (and not really releveant in a targetted thread such as a guide, openly derailed after the OP not withstanding).. I can usually tell when its about to go to that place i find really obsessive/bonkers. If i get a sniff of it, im usually going to say something
I also pointed out my opposition blocking ads on projects where the dev is probably getting a coffee out of every 100 hours of work they put in...and chosen to use an approved way to get some appreciation...i could literally block every ad on my phone without too much drama, but i choose to let people who feel they would like some form of appreciation to get it....
I also linked him to the Island thread where, and ive said this 5 times now?, he was likely to get more and speedier feedback, especially as the its thread by dev of the app, who would have a far better knowledge than i about how HMA might work across the multi user divide...i dont see how this is "not helpful".
BUT, just so we can move on and address the overall separate issue of HMA usage under multi user profiles....If
anyone knows
definitively if it
can be used under Island etc,
feel free to post it, ill add it to the guide and credit you, thats not the issue here. I simply did not like the way i felt the tone of the thread was going as the justification, if you like, for Island use was edge case and touched on something again i have 0 time for personally.
I would really like to stop rehashing things already hashed. The privilege i guess of creating a topic is you have some say over it. The member is quite welcome to open up his own thread and go to town. But i felt it was veering off into topics for which i famously have no stomach for, and considering i started the thread, i should be allowed to have some say in how it goes, i just dont want to keep taking hits for it...
Cat pics always welcome. I really do fear more mod interactions next year when ive finished building my Catio, especially as while unrelated and just because it popped up the other day up the road for sale 2nd hand, and for the same price as a MK2 new on black friday sale, i grabbed a Streamdeck XL, so while i plan to use it more as a workflow tool than streaming, it may feature a button or two to switch to an outside camera to throw to my remote correspondent.
Right now, im just learning to use and config it (i swear having it auto switch profiles to a particular app when you run that app and have 32 keys to do stuff in that app is the best thing ever invented), but its screensaver will look familiar to anyone who has visited my github....

Also as i shared with a friend, the first thing i did was set a button to Bleep, so i could employ swear button mode just locally in my day to day life

It feels like im very much On Air every time i swear now...
As
@pndwal and
@Stillhard know, i did look into setting up a Youtube channel for cat related hijinx, but i was knocked back on the username...i felt it was an unreasonable restriction, but it may have saved humanity from me having a youtube channel. I dunno, i might do a live "meet the freak behind that cranky XDA profile" at some point.
But please NO ONE should feel triggered at me having a Streamdeck, im NOT starting a full time
channel
To the left of the Streamdeck is my favourite gadget i own, a $12 (from Ali Express) USB switch...on the left (back) side of the switch are 2 USB3 cables, 1st (blue) goes to my laptop (which i use most of the time (power prices - with my G7 32" its about 60W) and the 2nd (black) to my desktop (somewhere north of 600W), on the right (front) side are 4 usb ports, and anything in those is switched when pressing the button on top to whichever PC you like, so currently it shares my mouse,keyboard, web cam and now streamdeck to whichever PC im using without a mess of cables and unplugging and replugging. Id like to tell you i arrived at this method years ago as an IT pro.....
(brief cat centric background - im soon going to have my first cat and companion animal in 22 years - took me 10 years to get over losing my bestie on New Years Eve of 2000, and then 12 years trying to find a place to have another - we have crappy rental laws here in Sydney/NSW that will hopefully soon be changed (got an update tonight about it) to stop a landlord automatically rejecting tenants with pets. For me it means i will finally have some company again - as with apsergers i do not do other humans in my space and have been single and alone for all of my life, and thats not going to change. A companion animal for someone like me isnt just about company, they help moderate and relieve stress and symptoms of my condition)
p.s. that cat in the bottle is totally me as a cat
