My understanding from the Megaplex chats and other folks is that there were complaints from attendees & other staff for the convention, that lead to a vote by the other board members for those 3 removals, and YappyFox was not happy with the decision and is calling it a hostile takeover, which is likely not what actually happened.
Edit; from the TG chat:

I believe the names are not up to date for the organizations board members, since there have been board member changes (without announcements) and more than the 3 listed.
Edit to avoid double posting, here are some interesting replies to the tweet.
Some people seemed really upset about this announcement because YappyFox and others have been there for quite some time, regardless of the reason for their removal.
