Tim Sweeney has been a big proponent of open platforms for over a decade. See also: the whole Apple vs Epic thing which was definitely not a good business decision at all. I think it’s possible this isn’t really about “incentives” and is just about sticking to certain principles.
I don't think that's him sticking to a "certain principles", he's just doing whatever it takes to make people think Epic is the "good guy", as long as he's doing the opposite of the competitors.
For example, take a look into his take about blockchain games. At first he was against NFT games [1], then after Valve banned NFT games, Gabe Newell talked about it [2], Tim suddenly was OK with it [3]?
He fought with Apple because he thought he could win it, so his Fortnite could avoid 30% transaction fee. They clearly had a lot of discussion, strategies before suing Apple and thought it was a good idea, they could have won big. It's not a bad business decision if he can win, but they didn't so it looked bad.
I could be wrong but it seems likely his first tweet was about Epic integrating NFTs into their own games, and the second was about allowing them on the EGS?
I don’t really see the NFT stuff as relating to open platforms anyway. Certain kinds of software (the most obvious being viruses and scams) need to be banned from platforms anyway.
