None of this is true, you seem to be making it up for the sake of attacking them. Google is often criticized and has been for years. That was never a bannable offense from the community chats. Nobody from GrapheneOS has ever doxxed anyone, for any reason. GrapheneOS has retained support from people in various security fields and that has only improved.

Alternatives to google pixels have been explored since the inception of the project. The only difference now is that an alternative is about to exist where one hasnt before. GrapheneOS was interested in paying an ODM directly before Motorola reached out. GrapheneOS has never been pixel-only for any other reason than limited options.

GrapheneOS has never suppressed criticism or brigaded on social media. What is often described as "criticism" is a thinly veiled excuse to attack the project. Real criticism has always been appreciated.
