Mastodon and Activitypub decentralize which means it is a lot harder to proverbialy whore yourself to the attention of the masses and and those attention whores (politicians, journalists,etc... not just celebrities and influencers) can't have the same reach with them or with truth social and other copycats of twitter.
Mastodon should have let server operators flag other servers but not refuse federation with them, letting users decide if they want to avoid content from trash servers but of course user moderarion by server operators is fine. Also, like many ideology-first solutions, it catered to small disconnected communities. It should have created corporation separate from the main project that hosts a public mastodon server that directly competes with other social media (and ffs, it's 2022, no more email for anything!).
On that note, Matrix can replace twitter and a lot more if they weren't chasing seemingly random features. Not just twitter but email also can be replaced by matrix, the api amd federates architecture allows for it.
If I was Kelon (Karen elon), I would compete with tiktok, timing is great with all the talks of banning it. They mercilessly murdered Vine back in the day as they did Periscope. Those are the types of features where you can charge content creators for content types and for advertising in people's timelines. They made those separate products instead of part of the regular twitter experience. Also, be less crass about it and charge for award tokens like reddit instead of upfront cash and high priced awards make it to the top of the reply chain.
I don't blog so let me know what you all think lol.
