Unfortunately a topic like this is perfect bait for a lot of the resentments folks have with the modern internet ecosystem.

There’s some rarely used tech that few have talked about in a long time. Tech giants have decided somewhat unilaterally to get rid of it because it’s barely used and has had security flaws.

There’s a discussion to be had about that specifically but most people didn’t care a jot about XSLT until it was threatened. What they do care about is tech giants controlling the fate of the internet. That’s a far bigger issue than can be solved in a GitHub discussion, but it doesn’t stop anyone trying.
