I think we are in early days on science communication but so far I haver fonnd Mastodon similar to Science Forums in that we can have good, intellectual conversation on a variety of topics.
I think what is important is perhaps people are open minded, are able to both challenge and accept challenges to thinking, provide evidence for arguments and we keep it friendly and civilised.
I don't think cancel culture has or will have a place here people will agree / disagree with a topic and viewpoint, accept that.
