Nah. That doesn't make a bit of sense, that's stretching those generalizations to the breaking point. How is talking negatively of it going to make it more appealing to people who already left mainstream social media out of dissatisfaction. Who do you think this person is who's like "I had enough of Twitter, but now that they said it's vile and falling apart I absolutely must go back there"?

Even if the average person on Facebook could vaguely feel interested in it as a talking point, which is already a strange logic, here it doesn't seem likely or meaningfully impactful.
