Who has an incentive to provide a Solid server? Not big social media companies, who want the personal information that Solid attempts to withhold. I don't think anyone is prepared to offer a convenient, high quality Solid-based social media experience to everyone for free, because that costs a lot of money. And if you know anything about human nature, it will have to be convenient and completely free in order to have a chance of capturing any mindshare outside of weird tech nerd circles.
> the platforms should be asking us what kinds of data they may copy from our servers, and only with strictly temporary allowances.
Until practical homomorphic encryption arrives, I don't see how this temporariness can be enforced. If we rely on promises or regulation instead of the technical ability to enforce this, how is that any better than today's social media companies promising not to do anything bad with the data they have on us?

Aka: I agree it can’t be dine with technology; it has to be done with regulation, and the EU example already models a lot of it.
'that costs a lot of money'
price of intelligence is dropping day by day like it or not, sooner or later price incentives for someone to host such social media experience could become financially viable
