If you're 10 hours into debugging something, or you're swamped with a horde of bug reports and bad reviews, and after digging in you find the bug is in upstream code laced with humor, it comes off as if upstream isn't serious about software development or is making light of the responsibility. Lots of things start small, but X11, Android, etc etc are now used by millions, in lots of different situations, and humor is highly contextual.
Sounds like a problem for outrage culture grumps, not not something people having fun with their code should care about.
