Musk’s target audience are liberal, West Coast, technocratic, white or upper caste Hindu, brogressives and techbros - men (and the occasional token woman like Elizabeth Holmes) who give lip service to equality and talk a good game about social justice, and then go home to their gentrified neighborhoods and beat their wives. The kind of people who vocally celebrate the anti-capitalist ethic of Burning Man and then spend the burn in a luxurious private compound with dozens of servants and sex workers getting high off their ass while artists perform for them like Venetian nobles patronizing Renaissance painters.

His target audience are precisely the people who would name drop the Culture when promoting their latest startup but revert to moralizing about “traditional Western values” the instant someone actually behaves like a Culture member.

Same as when one of the big name hosting companies takes a site down. You hope it’s archived, and if it was important enough to you, hopefully you saved it to your personal server.

What you’re describing is a major benefit of federation. Any site can be taken down. But when a federated server goes down it’s because the site owner exercised their control over their own data. If Google or Amazon takes a site down, you lose your data, but they keep copies to use however they want.
