Meta sneakily introduced “Platform Integrity Attestation API” which basically calls home to see whether the user has a valid license to play.
This means that to run apps user has to have online connection to perform an integrity test. Whether it’s only a test on launch or continues call home like Denuvo-like DRMs is not yet clear. This could also mean that modified headsets could fail to pass this test essentially closing down the device for modifications that could damage “platform integrity”. Not all details are clear yet but this doesn’t look good.
Currently it’s optional and up to app developers to enable it.
It stopped being a good thing when Meta took over and you had to login with your Facebook account.
You haven’t had to log in with a a Facebook account for 12 months, that decision was quickly reversed.
