Ask HN: Why are people so mean in the open source community? (about xz again)
Browsing the xz repo in GitHub and checking the recent entries in the Issues tab, I just found this entry:
https://github.com/tukaani-project/xz/issues/121
The person wasn't able to compile the project and he starts by being mean when he asks for help:
- "it shouldn't be this hard"

- Xz: Update maintainer and author info. The other maintainer suddenly disappeared

The xz sshd backdoor rabbithole goes quite a bit deeper
> The payload of the 'hack' contains fairly easy ways for the xz hackers to update the payload. They actually used it to remove a real issue where their hackery causes issues with valgrind that might lead to discovering it, and they also used it to release 5.6.1 which rewrites significant chunks;
The valgrind fix in 5.6.1 overwrites the same test files used in 5.6.0 instead of using the injection code's extension hooks. This is done with what should have been a highly suspicious commit: https://github.com/tukaani-project/xz/commit/6e636819e8f0703... - this replaces "random" test files with other "random" test files. The state reson is questionable to begin but not including the seed used when the the purpoted reason was to be able to re-create the files in the future is highly suspicous. This should have raised red flags bug no one was watching. I'd say this is another part of the operation that was much more sloppy than it needed to be.

GitHub Disabled the Xz Repo
You're right, but maybe because there's nothing to see : https://github.com/tukaani-project/xz
- Xz Repository Censored by GitHub
- Backdoor in upstream xz/liblzma leading to SSH server compromise
