Absolutely. There is a lefty-oriented echo chamber already on X, a remnant of the Dorsey-run site. Still relevant, active, free to do it's thing. Musk liberated X, allowing for alternate views by lifting the censorship. Result? Real competition of ideas in the marketplace expressed on a major social media platform.
Who would want to be against that?
Lefties had so enjoyed the heavy-handed censorship of the earlier twitter, leading them to a false belief they were right, and owned the market with their views on political and other issues.
Not so fast, it turned out. At least since Musk acquired it, that is. And now with the '24 election/rejection of the dims and Harris in the books, and their utter shock of Trump's victory, one of their scapegoats to explain it is X.
Just another moment of the "You want the truth? You can't handle the truth!"
So now lefties doing what they do best. Flee in the face of truth and reality. Gotta get to a 'safe space'. It does provide a chuckle or two when reading all the "I am/I will be leaving X because.....". If bluesky didn't exist, you'd have to invent it.
