There is one huge difference here between this and NFT/Play To Earn schemes
In both NFT/P2E -- they promise physical cash (or at least some mechanism to cash out). NFT/P2E bill themselves as mechanisms to make money - either by grinding out a paycheck or via investment value / appreciation. And then they have some sort of a exchange where you can cash out your in-game earnings for real, physical currency. (I would argue that Steam trading cards are NFTs as well, although one could also argue that NFTs need some crypto component for whatever reason and Steam lacks that)
Here, Sony may be offering up trophies, skins, collectables, etc... but they have always done that really. This is just a wider roll out. And there's no mechanism to cash them out -- so no Play to Earn or NFT cringe factor. Yeah, loyalty points -- but they've had that for a while too, it's just been obscure and hardly used... and it's able to be cashed out either - not really any different than getting a coupon in the mail or those grocery store loyalty rewards or something.
