GrouchyGrape I don't see any problems with it and I think you're seriously overestimating the effect that this thread can have on that matter. Especially since there's already chatter about it elsewhere.
So no, I don't think there's reason to worry. Especially not in regards to the OEM sharing the code. GrapheneOS is already quite open about that and bring it up unprompted. When the OEM is named, it'll be revealed anyway. Or will it? It could be they got it from a different OEM.
And most importantly, nobody here actually knows anything. So what is anyone gonna do with this loose speculation, and quite frankly, mere guesses.
It's speculation from random people on the internet. It's not like we're leaking documents or insider information. 😛 GrapheneOS haven't requested that people don't talk about it, as far as I've seen. I think they expect it. Maybe they even want some chatter, to get the word out. 🙃
Like others say, it's all for fun. Some people like to speculate. Some don't. 🤷♂️
