I don't really follow politics so I have no idea what you're saying with DeSantis.
The Florida governor wanted to show off his tech savvy by announcing his presidential campaign on Twitter. It quickly devolved into the conference call from hell.

TL;DR Twitter spaces crashed for 25 minutes when Elon tried to host DeSantis announcing is presidential candidacy.
The significant issue with Twitter stability is that most problems are not obvious externally (we've had those too - the whole country of Australia losing access for hours, numerous instances where the app cut out, rate limiting people's access to view messages).
The architecture is such that there are systems that look at 'streams' of messages to perform certain functions. Optimize advertising and provide metrics. Build the algorithmic timeline. Handle notifications of responses to your tweets.
A good number of those have been partially broken for MONTHS now. While there are people who left because they could not stand Musk, a lot of creators left because they could no longer interact with their fan base - they would not see if someone asked them a question, for instance.
That's also the issue with letting go of such a large portion of the workforce. The reason it was built to have these independent processing functions on the 'firehose' of twitter messages was also organizational - it let a small team be focused on _just_ advertising metrics, or _just_ a certain type of bot detection. My understanding is some of those teams were cleared out completely; so there is nobody left who knows how to fix the problems in what amounts to a completely different codebase than what they normally work on.
You might be able to spread out workers to run those as even smaller teams, except the focus is on new features and new sources of revenue, not putting out the existing fires - and the pressure is high enough that things ship half-completed, like the transition to X.com before they even had a finalized logo.
But plenty of famous haters assumed Twitter was going to shut down back in November. The fact that it's still running (not perfectly, but still alive) with 20% of the staff is incredible. Elon absolutely knows how to trim the fat (again, not perfectly, but effective).
It isn't really Elon's pick of employees or leadership style there - the entire architecture is built for resiliency against failures in non-critical systems. that they have had problems with say Android phones not being able to connect for hours on end is more a testament to how seat-of-pants twitter-nee-X is being run now - before, changes would have multiple checks and contingencies to prevent such a long-term full outage from happening.
From what I've seen, more and more creators who used to just post their YouTube links are now actually embedding the full video onto Twitter.
Probably. Twitter seems to be paying way above market rate, and there's no exclusivity contracts that I know of.
