Since you are a junior member and XDA stopped being anything like what you are describing more than 2 years ago I'm not sure what to make of your post or even if it's legitimate and not another of the many fake posts associated with a rival company that XDA actively shills for.
The last time XDA was free, honest and developer friendly was in the Nexus 6P and OP3 days. By the time the Pixel XL and OP5 came out XDA was actively hiding negative information about both phones from its members, Google had become anti-development and created safety net to block specific apps from working on modded phones, the developer of SuperSU threw in the towel because he saw no future for Android custom ROM development, paid tools, services and apps started turning up throughout XDA which also started regularly publishing articles that were sponsored by specific companies.
If you knew anything about Android phones then you should have known before buying the M20P (assuming that you actually own one which is unlikely ) that Huawei stopped providing bootloader unlock codes over a year ago and that if you wanted a phone with an easy to unlock bootloader buying the M20P made no sense.
Why would anybody spend $800 or more on a phone by a company that doesn't want you to unlock the bootloader and then complain about trouble unlocking the bootloader?
Your post would have been plausible a year ago but it isn't now.
I agree with everything you said.
But maybe 'cause english is not my mother language, I haven't made myself clear enough.
Yes, I miss the good old days of XDA. As I said, here in the community I customized and fixed my Galaxy S4 several times. But I never registered in the forum. I just followed the posts and gathered information. You can call me a vampire if you want. : ) But I'm not a fake or even associated with anything.
Like you, I also miss the "free, honest and developer friendly" days of XDA. And I also never done anything that could vilify the community.
I continue to follow the news here. And at this time, seeing all the controversy involved around this subject, I login and exposed my opinion about it. Making it clear that I am also saddened by this new overbearing Android doctrine and that I also miss the golden age and freedom here at the XDA.
About my device, I don't have a Mate 20 much less a Mate 20 Pro.
I got a Nova 3 because I found one in a pretty good sale and I also wanted to get know the Huawei hardware as I said in my post.
But since the Nova 3 forum is practically dead, I came here to leave my opinion on.
You are right my friend. In everything you said.
It's really shameful and sad to see that the same people who brought this community to the world, are now only tainting their own legacy.
Be well my friend. And once again, sorry 'bout my English. ; )
