Please, just pick a side.
"I want to be the selfless craftsperson giving away work for free to anyone, but I'll also pressure profit-maximizing evil mega-corporations to give me money from the good of their heart, despite the fact that I've explicitly stated in the license they don't have to" is just not a smart position to hold.
If you want evil corporations to have to pay money in exchange for using your software, add that as a condition in the license. Ah, but then it's not "free software", sorry.
There's so much unexplored space in licenses that achieve better outcomes for both the developers and their non-giant-evil-conglomerate users, but nobody is willing to touch that subject, because then they're not writing "real free software" and the "FOSS community" will not use it.
I suspect github might be preventing some price discrimination. If you got feature request from @amazon.com you could point them to your commercial support offering or something. Some namehandle filing an issue on github makes it less obvious who's asking for it.
Personally I don't trust companies not to rip me off regardless of the licensing.

Am I wrong that this is orthogonal to "pick a side"? It sounds like you're suggesting that the sides themselves are inappropriately drawn.
