Your two comments show you’re the perfect audience and user for an Elon social platform. Every failed or failing Twitter esque platform has some number of perfect audience fits. The problem is that those aren’t enough users. There is no reason to believe an Elon venture would fare markedly better.
The amount of users who once used twitter minus still use twitter is greater than current twitter users. You could build off of everyone rejecting twitter.
Most people who have “rejected” Twitter did not do so because of Twitter issues but wanting micro blogging sort of social platform.
Most rejected the overall concept. The amt of users that stil want something similar but not Twitter AND who will be appeased by whatever alt Twitter is made is an even smaller number.
That only makes sense if everyone who stopped using Twitter is some kind of united cohort. Many people were simply not interested in the format, didn't find content that cared about, didn't have friends using it, drifted off to other social networks etc. Good luck gathering all of these people together on a new platform.
