Oversight on Featured Servers

Featured servers can be fun and interesting offering a new way to play the game, I recognize they aren't directly controlled by Mojang but when they're added to the featured server list it would be nice if there was some accountability and predictability.  

I've played on several and for the past 6 weeks I really got into "Treasure Hunt" when it was added.  It's fairly heavily monetized and I was softlocked for a couple days because of monetization but the advancement still had fun mechanics.  Today logging on I just saw they made an unannounced update that took away the majority of the collection and advancement over the past 6 weeks.

It's obviously not a direct issue with Mojang but if Mojang is featuring them I think they should hold them to a higher standard, featuring them is giving a form of company approval.  These sort of quick changes which effect player experiences starts to cheapen the franchise over time.
