Yes, and nominally so did homeownership in suburbia vs rental in overcrowded cities. What it actually meant is that instead of being beholden to "The Man's" cultural standards, they were now beholden to the Homeowner's Association's. Instead of overt racism and segregation, they got redlining, blockbusting, and racial steering. Instead of razor thin walls leading to informal surveillance, they had to Keep Up with the Joneses.
Of course, the forces are now politically/socially based rather than fundamentally racially based, but the principle remains the same. It's another digital White Flight by any other name.^1

You’re assuming that urban is always superior to suburban. There are many who prefer the problems you call out vs the problems with urban centers.
Self hosting a service will of course mitigate all of the issues you listed. The control shifts from a company like Facebook into the hands of the server owner.
