I don't want to excuse rudeness or a sense of entitlement. But I think we can still understand where it comes from. A lot of these people probably work on crappy codebases where "let's just add a random dependency without any vetting" was the norm, they might have to deal with production issues etc. There's probably a systemic issue behind it, that our industry relies too much on unpaid labour and is usually not willing to contribute back.[0]
[0] Funnily enough, just a week or two ago, I fixed an issue in an OS project that we introduced at work. It was an easy frontend fix even for someone like me who doesn't do frontend and barely knows how to spell Vue. And more importantly, in the issue description somebody already wrote exactly what causes the bug and what would need to change - the only thing left was finding the place where to make the (one-line) change. Somehow that issue had been open for 2 years but nobody of the several people who complained (nor the maintainer) had bothered to fix it. After I made a PR, it was merged within a day.
