vitalik buterin was a very logical move to me. He sold the MEME coins he received and converted them into money. This is something anyone will do when realizing that MEME coins have no future. I would do the same if I could get it. and because he had a huge amount of MEME coins, he turned it into huge money. however, some MEME coin supporters were uncomfortable with this situation. It's hard to understand why they also support MEME coins.
I think it's just a warning from vitalik to not mess with him by sending some tokens to his address purposefully for "burning" while at the same time advertising their tokens since you know it's vitalik buterin's address we're talking about where there's a lot watchers of that address and he didn't really sell of all the coins and left 90% to a burning address, basically he gains nothing from doing that act and going against the meme coin communities.
