Ditto.
As
@Right_Said_Fred points out, it's definitely on topic for this board, because they interact with Elon constantly on Twitter and this is not good for their mental health (they crearly enjoy too much to be in his shadow) and him (because he's human and if everyone agreeswith you all the time clouds your judgment).
Elon's ego it's already big as it is (only a ego like his could accomplish the things he did, so I understand the advantages),
and Twitter is a very, very shallow and imperfect medium for reasoned discourse.
If your interactions are just with trolls and yesmen things can't go well, it's too polarizing and I don't know anyone on Earth who could remain level-headed all the time.
Reasoned critics are good for Elon too.
