Yes, the Reddit dev team might have spawned a 2000+ repo mess, but they also host it under the snooguts.net domain name, which is objectively adorable, so all is forgiven.
It always seemed so perverse to me to promote this sort of tacit approval--as you say--passing it off as "cute" instead of... improving things.
Having seen this sort of thing many times, and being in that position myself, it seems more about it not being the "rank-and-files" responsibility to fix these things. I'm not going to deal with the process and bureaucracy in order to (try to!) fix processes that are above my paygrade - and with no guarantee things will change in any way
In short, this is a sort of coping mechanism
(Obviously this is less applicable to upper management)
