(Baseless conspiracy theory) A couple of months back, Elon decides that Twitter really is evil, so after confirming that Twitter is more than 5% bots he hatched a plan to send them to MySpace land. He psyches everybody up with his big offer, and at the last second, he leaks audio that Twitter doesn't believe in free speech. He then gets out of the deal for nothing, using the bots as his escape.
Now that Twitter is on the way down, he buys out TS and lets ppl know that TS is the way to go. TS overtakes Twitter and we look back at this moment in 20 years as the moment that brought free speech back in the US.
