The transgressions are not assumed. All they've done is reverted a small piece of DRM that was leading to piracy. They have not opened up their store at all. It's still completely closed to non-Oculus hardware.

Perhaps you're missing context to understand why people are upset. Oculus has went so far as to actually pay developers of open, non-exclusive VR games to restrict their games to the Rift and Touch only, either indefinitely or for a period of at least six months. These are games that were already in development. In one case, people had even pre-ordered Giant Cop for the Vive through the Humble Bundle, but Oculus purchased timed exclusivity rights for the game afterwards.

It's a really nasty situation, and Oculus deserves every bit of criticism they've received. This reversal of a tiny piece of their overall exclusivity strategy does not in any way diminish or undo everything else they've been doing. In fact, it's completely irrelevant for anyone who wasn't planning on pirating content.
