The guy makes shitty posts (literally he seems to have some scatological obsession) no one likes them and then he complains that he's being suppressed.

He's been doing it for a while now, before Elon took over he blamed it on his right wing views being suppressed, and Elon took that at face value and took up his cause as one of the reasons to buy Twitter.

Now I guess he's coming up with a new conspiracy that everyone is getting suppressed. In reality it's probably that people are just disengaging from Twitter and there is less views / engagement to go around.
