I am not sure, but I believe that this political abuse is further reinforced by something not mentioned in the text:

• Twitter is mostly short texts, lacking situational info, subtlety, signs of doubt, etc. Those require a lot of contextual info to accurately understand, but as a piece of content is retweeted most of that context is gone.
• plenty people are not honest; they’re assumptive as a brick. They make shit up = assume = bullshit as it goes, never acknowledging “hey, I don’t actually know this, it’s just a shower thought, it might be wrong”.
• people holding minority views are more often dogpiled, and by bigger dogpiles, than people holding majority views. Kind of like the Petrie Modifier, but with worldviews instead of sex.

It’s breeding grounds for witch hunting: people don’t get why someone said something, they’re dishonest so they assume why, they bring on the pitchforks because they found a witch. And that’s bound to affect anyone voicing anything slightly off the echo chamber.

And I think that this has been going on for years; cue to “the Twitter MC of the day”. This predates Musk, but after Musk took over he actually encouraged the witch hunts for his own political goals.
