Speaking as a FOSS maintainer, typos should be trivial to fix as long as it's in a language the devs are fluent in. The kind of up front work you mentioned putting in to your tickets is practically the platonic ideal of a good issue.

Speaking also as a corpo codemonkey (like the people at Bethesda), management and product consistently — through short-sighted hair-brained schemes and giving zero shits about what actually goes into making a software product — raise a shit ton of barriers to getting even simple things done. This leaves little choice but to make quick but shoddy ways of implementing features to meet the deadline, which in turn creates tech-debt which is itself a barrier.

I could understand the "just make a pull request, bro" response if someone comes in demanding a vaguely defined feature that seemingly no one else has expressed interest in. We've used that answer several times for issues raised for Lemmy. In your case though, the response seems unwarranted.
