I found this Veratasium documentary on the xz Jia Tan backdoor adventure quite good and surprisingly detailed:

The Internet Was Weeks Away From Disaster and No One Knew

@bagder I wish they had left Stallman out of it though. He's a very problematic figure. While I do not discount the contributions he has made to Open Source and Free Software, his "other" public statements make me stay far away from everything to do with him.
@infosec812 @bagder bullshit argument. No one excels at everything and attacking or hating him for his weak points while overlooking his contributions to society is horrible behaviour. Without him, the world would probably be a very different place today

We'll have to agree to disagree. Just because someone does some good, it does not excuse inexcusable behavior.
@bagder
@infosec812 @bagder having poor social skills is not inexcusable behaviour, in spite of what the pitchfork wielding crowd would have you believe. In fact I'm still waiting for the world to become a better place after his removal and I only see everything going downhill harder than before
