Most jobs that work with FOSS are at the most privacy violating companies unless you go to (eg.) ARM to be a compiler engineer.
Other than that, your best bet is meta, google etc. as they have the resources to pay to write code for other people.
There’s a difference between being a team player and a subservient pawn though - if the maintainer wanted to play as a team they would’ve suggested changes to the patch and accepted OP’s PR. As it happens they didn’t as they clearly have some sort of a power/superiority complex or something, or at best are dismissive of others to the detriment of the project they work on
Yeah, gleam.io really fucked up I guess…
