It's additionally ridiculous because git is a code management tool. Maybe they are using it for something much more wild than that (why?) but I assume this is mostly just a complaint that they can't do `git pull` from their wonky architecture that they are building on. They could literally have a network mount and externally manage the git if they still need it.

It's not like older versions of git won't work perfectly fine. Git has great backwards compatibility. And if there is a break, seems like a good opportunity for them to fork and fix the break.

And lets be perfectly clear. These are very often systems built on top of a mountain of open source software. These companies will even have custom patched tools like gcc that they aren't willing to upstream because some manager decided they couldn't just give away the code they paid an engineer to write. I may feel bad for the situation it puts the engineers in, I feel absolutely no remorse for the companies because their greed put them in these situations in the first place.
