Big ones are: shadiness with funding, letting their SSL certs expire 4 times, and the fact that their idea of stable isn't additional testing, but just letting the packages sit for a week.

There was also a recent kerfluffle not covered there where they shipped a broken kernel to Apple Sillicon users without contacting the Asahi devs: https://twitter.com/AsahiLinux/status/1576356115746459648

The recommendation from the repo, EndeavourOS sounds interesting, though.

The link for the post is dead, but they've let their SSL cert expire multiple times. While it happened a few years ago, I find that a hard thing to come back from.
