TGC asking Beta testers to start over

So since Beta continues to not have new invites, TGC is asking for 'volunteers' to completely erase their progresses to test our a feature for new players with no reward or restore afterwards. And I can't believe people are actually doing it? There hasn't been an invite wave since Aurora on iOs and Moments on Android, so everyone who is in beta is decently old I can't imagine doing this just to test out something the company could perfectly do themselves and be able to get all their cosmetics back by re-adding them to their own accounts.

Why can't they just make a new invite wave filled with actual new beta testers? and if beta servers are full why not remove the inactive accounts?

anyway just wanted to complain about this because it's so baffling to me, glad it's voluntary so I don't have to.
