How does this differ from the deplatforming we've recently seen with Twitter, Apple app store, Gab from hosting providers, facebook, youtube, etc?
Now, if my tax dollars helped pay for Twitter's datacenter, then now we have something to talk about. And perhaps in the state where Twitter is, they got tax breaks which amount to effectively a subsidy from the citizenry. In that case I think it's time to take the case to court.
I am someone who believes that private businesses should be free to discriminate with regards to whom they provide service but we are faced with varying degrees of subsidization and I'm not sure where you would draw the line. Another issue is that there is really no non-subsidized alternate choice of note to these corporations at this level in the United States. These large corporations lobby and help craft favorable legislation on a continual bases. There is a very complex and murky relationship between the large corporations in the United States and the various governing bodies.
Some of these accounts that were de-platformed completely erased followings that they had developed over years of working that were probably worth millions of dollars to them. To imply that you finding a different ISP is a greater inconvenience than what these businesses had to face is doubtful. Even if you had to completely move to a new home to get service it could be argued that it was still less of an inconvenience.
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.
Now I'm not saying it's completely the same, but often it seems like the piracy takedowns set up the playbook to censoring things that often affect lots of peoples' lives.
I'm very vary of corporate censorship since it's an easy next step for politics and the government to start wielding it against the people. And that could be disastrous.
I think OP's point was that if this bothers you and the recent de-platforming of people and websites does not, maybe you should rethink your position. But maybe I misread OP?
