Exactly that is my fear, too. It's like zero trust in everything. - Don't trust that any other party do the security testing for you - Don't trust any developer, it could have malicious intents - Don't trust the patches, they could introduce bugs/backdoors/...
So we're straight going in the direction of protectionism and isolation. Wouldn't that be a big step back for the whole OSS/FOSS community?
One thing I read the xc-writeups last days (I think it was here https://gist.github.com/thesamesam/223949d5a074ebc3dce9ee78b...) was that we at least shouldnt trust any devs/maintainers that have no online identity. Though the argument that you could create a fake ID is possible. So I'm still obsessed from the question, what are the lessons learned for the community from this and how restrictive the participation in OSS will become.
