If I’m completely honest, after reading both your account and theirs, I don’t really understand why you’re this hung up about it.
It’s almost like you care more about credit than a port that actually works. I know you weren’t done/that it was a WIP, and they told you to wait, but at the end of the day it’s open software, and literally anyone could have beaten you to it.
I don’t think you’re wrong to feel that your efforts should have been represented more, but I honestly would have backed off like 10% through that conversation and just started working on something else. It’s not worth it man. I hope you can feel better about this whole situation soon.
Because the USA loves inventing problems to “”solve”” (see: literally the entire military industrial complex)
