As much as I liked Perl back in the day, it did sometimes earn its reputation as a write-only language!
At my company they really locked in the project being dead if the original contributors left.
Perl propped up regex (JavaScript regex is based off of it), so I get the impression Perl practitioners tried to make all the code regex-y as possible as a cultural thing.
My main source of support back when I did much Perl (late 90s, early 00s) was usenet, and while some groups were very snubby and elitist others were very helpful and encouraging for a young budding programmer.
And this became a joke and meme.
