predatory, mafia or middle-age money lender style.
Your words have lots of sentiments, but present no facts. I know that Wolfire and Sweeney are independently throwing a tantrum, and we all hate taxes, but I don’t see public exposés showing game developers who went hungry because they couldn’t afford the 70-30 split.
I’ll also remind you that the EGS (12%) is barely profitable, and operated for years at a loss, only sustained by Fortnite (which used dark patterns to extract money from kids, in case you want to see something actually predatory).
Counterpoint: if you have the ability and willingness to learn how Linux works, un-fucking a broken Arch installation will teach you more about the system than spending months with a stable distro. I know because my first serious daily driver was Manjaro.
