This is one of my largest frustrations with the open source community. Everything is immediately assumed as malicious. There is no escalation, it's "you screwed me over" from the jump.
I suppose it's bred from decades of large corporations pilfering open source for profit. However, this post could easily have been, "I noticed there's some code I wrote that wasn't attributed, would you mind adding that?". Escalate from there if the appropriate actions aren't taken.
In LitigousEmma's defense, kbin did not comply with the license terms of the open source software, so there is a valid concern here. Unlike most programming languages which are often released under licenses which do not requite attribution.
However, mistakes happen. The open source community is better off if we could all just start from 0 and escalate based on response.
This is the solution. With enough small instances, not only do we provide a wide range of options to users, but we also distribute the hosting costs across the community.
My favorite version of this is when the novice has followed someone's dodgy advice to set pull.rebase = true, then they pull a shared branch that they're collaborating on, into which their coworker has just merged origin/main. Instant Sorcerer's Apprentice-scale chaos!
