I think this is kind of reductive.
I mean it's a nice narrative and sounds like what we want to hear but is it really true? Trump has had his metaphoric pants pulled down a bunch of times but he has more influence than ever.

I'll never call it X.
It's twitter. Perhaps xitter if you must. On mastodon it's universally referred to as "the other place" which is acceptable.
