>I'm at least confident if my ISP started blocking Netflix because they made a deal with Comcast, the hammer of the FCC or FTC would fall on them in short order,
What? What has possibly ever lead you to believe this? The FCC is doing everything in its power against massive popular demand to ensure that Comcast can do exactly this even though everyone is screaming about hating it. Perhaps Netflix would accept paying massive bribes to prevent this from happening, but the current FCC will never step in.
>I have no such confidence that Google or Apple will be forced to allow, say... Gab... ever.
I agree with you here, the monopoly and walled-garden system we use for phones is very bad. Users should have ultimate control over their own machines. And this should perhaps be mandated by law, i.e. mandatory jailbreak switch.
>No consumer outrage nor any movement by the FTC or FCC.
There is no consumer outrage because nobody cares about Gab, it is a niche service for extremist conservatives who were kicked out of other platforms for doxxing, horrifying racism and advocating and organizing violence and genocide. The twelve people who would use it connect through Tor to the daily stormer and are just fine.
If you can't download the Gab app, you can still connect through the web to the service. Iphones don't ban visiting certain websites. Your problem is that Apple controls what you can install on your phone, because the Apple ecosystem is closed and censored, but the web is open. But not for long. If your ISP blocks your connections to the Gab servers, it doesn't even matter what you can put on your phone.
It seems to me you want NN and also something stronger than that, which I'm completely on board with.
