However any sort of payment please let me just earn credits. Other sources ruled my classification about it over MIT
How game publishers on Stadia get paid is well beyond the scope of this forum, but I can't see them changing the whole structure of how it works. If you're talking about the MIT license as far as I know there is nothing about the MIT license that restricts getting paid for your software in ... money.
I do not want to get paid what so everf i would like to offer services as a volunteer based. I am disabled. I can't handle the stress.
