Given your tone, I'm going to guess you're not asking the GP a question in earnest. You should try to think about why they might "give a shit".
Twitter's userbase is its primary feature. Not its shitty UI, not its awful character limit, and none of the stuff mastodon's various UIs are copying. Its userbase.
If you want the fediverse to succeed, you need to understand that. And you need to stop being so accusatory of people who don't use the internet the same way you do, FFS.
(And for the record, I want the fediverse to succeed, but I also use Twitter because userbase)
