They are spying on you. These HIDDEN accounts are there and the sheep who use stock android can't see them because they are HIDDEN in stock Android. They keep adding themselves back, they check themselves even if you unckeck them, they sync things you tell them not to sync, and it's NOT because you update something as I have not updated Cyanogenmod from 4.4 and it happens every time I start my tablet. Google will keep spying and can care less if its illegal to keep syncing things you don't want to sync because Google owns the US government. Google saved HHS when ACH Website failed, they have imbedded themselves so far into the government they are like a cancer that can't be removed. The US Gov "lent" Google GeoSat, one of our SPY satellites to make Google Earth, something that cost tax payers a lot of money. Google may provide Google Earth for free but they STEAL your personal information when you use the service, which means Google got free use of a US Government, taxpayer owned, SPY satellite so they could make more money for their private (not government run) company. Google gets free & subsidized aircraft fuel from NASA for their fleet of Attack Jets (IE fighter planes) also subsidized by WE THE PEOPLE. I am not some conspiracy theorist; I have worked for both sides of the isle on this one and can tell you Google is a problem.
Let's be honest, XDA has turned into a bunch of fanboys; it's not the site we had years ago. I have been fighting this crap for years (Look at my post history) and if you have not figured out yet, most of us who cared about privacy left XDA years ago. This is why no one is responding here; no one left cares. You are very correct, Google Play Services is MALWARE in disguise. I am not a crApple lover at all, and still use Android (for now), but am sick of Google's crap. I ported out my Google Voice number today and now have very little left to do with the company.
Google services is a framework that GApps and most stuff downloaded from the Play Store rely on to function. It used to be you can disable it and still have apps work, but a lot of them now wont even load if its removed or disabled. Google says its a way for app devs to take shortcuts, but it's there for one reason: Make App Devs LAZY so they they use Google's SPYWARE. App Devs (even most paid ones) don't give a crap about your privacy; most are adding ad code so they can steal your personal information. Google loves this as it opens up your device to have everything stolen, by not only Google but 3rd parties. Why do you think Google removed the ability to block app permissions then claimed it was a dev only feature? Google could care less about your privacy.
I sent the three main Google guys (@Google email not
@gmail... Yes I know the Google Guys Real Emails) a project proposal from the company I own two years ago; they [legal, but Shady] stole the idea and nine months later made the announcement that in a few months they would be starting on Android Auto. My SMS messages going through Google Voice started to have issues shortly after with anything concerning to business coming in slow or didn't arrive at all, my Google+ posts were blocked for unknown reasons just saying they "didn't fit the community guidelines", and my Camera/Mic was constantly pushing popups saying they "couldn't start as they were already active" when I tried to use them on my Android Devices. I don't know why it's so hard for these sheep to believe a $500 Bil company, one of the most powerful in the world, wouldn't be spying on competitors or even stealing ideas from the community. I wouldn't be shocked if these creepy elite weirdo's havn't come up with their own version of "unReality TV" where they just spy on regular people like watching a television show. They are creepy vampires, all of them. I have had dating emails sent to gmail from the dating site I use not arrive despite the company I use tracking down the emails and saying they made it to gmail servers and thus should have gone through, client emails be delayed until after project deadlines, phone calls not make it, SMS/MMS delayed and/or lost, etc. I have people telling me they emailed or called me without reply, etc. My PC is virus free and My Android Tablet is as well. I now use a dumb phone and forward everything to that number, which no shock the dumb phone works when people call, but anything that goes through Google servers is still hit or miss. No one I know has these problems, but no one I know has called Eric Schmidt some foul names, so I guess people will say "it's my fault". Whatever; you just didn't get robbed several billion on a project by a garbage greedy scumbag company.
Screw Google.
I have attached a little of what I am talking about because the net is filled with BS. The I had to block out a lot of the proposal email as they only stole part of the idea so far and this was my SECOND email. The first one has some how gone missing from my sent box, but had a DOC attachment with a formal business proposal. That went through, but as you can see from the screen shots, Eric Schmidt has now blocked me with a policy rule on his email. Again, they received the original proposal back in January of 2014, before this screen shot of the second correspondence, after which they started blocking my Google+ Posts and when I send this second correspondence email I found out I was blocked by Eric. Nice! Steal my ideas, try and cover up email (missed one! OOPS!) then block me! Google "Does No Evil!" Oh wait, Google is nothing more than an advertising agency pretending to be a tech company... I guess thats where we get the lies "Do no evil". Everyone knows advertising lies.
