That is called “refund”

If I buy a game that requires a launcher I immediately return it and give a very long and detailed description as to why that’s not a product I can buy as I do not own it.

Launchers should do just that, to launch the game. Doing anything other than that is, before anything, a repurposing of the word.

And regarding this specific game, I didn’t see the whole struggle so I don’t even know which game it is, but in case it is officially sold anywhere DRM-free, I strongly suggest going for that, wherever it may be.
