As a VR developer I'm really sad to hear this news. I've always been against the walled garden approach. I feel like it's only a matter of time before they block SideQuest.

However - supposedly your oculus account will be valid until the end of 2022 [0]. At that point you could change to a newer hardware platform from another manufacturer.
