Instead of @TeamYouTube removing checkmarks, they COULD have just added a new type of verification for these high end brands or whatever the heck they are talking about. But that would make too much sense.
I'm sure they won't reply to any of these tweets for a few days, but Twitter is a dumpster fire about it right now. "Give it a few days, and they will all cool off" is what they are thinking, but they are going to have to respond soon. It's too big to sweep under the rug.
