The only thing that makes it notable is probably the reason. It's interesting that this topic is so polarizing. Especially where VCs are concerned.
Personally I tweet pro and con Web 3 stuff and every time I tweet something critical I lose on average a couple followers. The Web 3 devotees don't want to hear anything critical.
As an anecdote: I've never blocked someone in my 10 years on Twitter so I'm not sure how "normal" it is.
