If I didn’t visit Lemmy, I wouldn’t even know how many people dislike them

“Many” is probably an overstatement. Lemmy echochamber is probably like 1% of ultra-leftwing Americans. Even among their country left wing is a minority. And overall the US is less than 5% of the world population. So for every person hating Musk you will probably find ten thousand who adore him. Just not on Lemmy.
