It seems that some Bitcoin community leaders are very scared of Satoshi Nakamoto.
"Bitcoin supporters" is a better phrasing, but which ones do you have in mind? I don't see anyone "scared" of Satoshi. Insanely curious, yes. Scared? I wouldn't say so. I'm more scared by the decisions of people like CZ and Brian Armstrong, rather than Satoshi.
They are trying their best to spread too much fud about Satoshi Nakamoto's identity revelation. They are trying to stop Satoshi Nakamoto to reveal his identity.
All Satoshi had to do all those years was to sign a message, and it'd be more solid as evidence than all the noise we've been hearing for 15 years combined. Apparently, nobody is trying to stop him from revealing his identity apart from himself.
