Earlier quoted context omitted.
There are a lot of platforms to choose from, but my house is only physically connected by one high speed ISP.
I think you are oversimplifying here. The de-platforming often was sweeping across many websites and service providers. So there weren't really any choices left. And in the case of Gab.com they have had a lot of trouble getting running again at all. I think they were completely shutdown for a week or so. Some of these accounts that were de-platformed completely erased followings that they had developed over years of…
In any case it is still much better to have multiple providers to possibly be rejected from, as opposed to a residential broadband subscriber who can be completely shut down by a single company. And Gab.com is not a person, so they can locate their service anywhere someone will allow them to host it. The virtual nature of that arrangement is very convenient, and the relative inconvenience of buying a whole new house (in a different city or state, perhaps, since you have to move far enough to find a different ISP) is off the charts by comparison. It seems disingenuous to even try to compare those.
