Earlier quoted context omitted.
He'll block you on twitter for politely quibbling with his presentation of facts.
Is there a deeper meaning to take from this? Some people block anyone negative on Twitter. He's free to use the platform as he pleases, I see no reason why someone should feel obligated to have or present an externally valid reason for blocking others.
On the other hand, when someone confidently opines about a lot of things and then rejects mild corrections (I literally just said something like "thing isn't part of B, it's owned by the same parent company"), you wonder what facts are feeding into those opinions.
