Irrespective this thread is not about who is or is not burnt out, it's about how posts like your are what enabled the xz backdoor to happen.
I thin you need to chill a bit. Open source has a long illustrious history of people cooperating to build software and submit patches and enhancements which are then scrutinized by project leads. Yes, occasionally bad actors use this model to try and slip through exploits, but you don't throw out one of the strengths of open source because of that. You make sure mechanisms are in palce to allow robust scrutiny.
And no, I'm absolutely not going go through someone's post history and quote bits that show someone is frazzled. I expect you to have enough empathy
