I’d say all that is fine as long as your first and second sentences hold good.
If matters progress to a stage where the only realistic way to take part in public/social life is via one of these platforms, then those principles can no longer apply.
I don’t think most of the world is there yet but Cory makes the point in his article about the situation in Cambodia where he claims:
I don’t know the details of that but I can say that up until a year or so ago here in my neck of the woods if you wanted to take part in any sort of social activity (sports club, etc.), 90% at least of the the coordination and dissemination of information would have been via a Facebook group.
If you weren’t on Facebook, you didn’t get to know about whatever is going on, meet times, etc.
Nowadays, I suspect whatsapp takes over a lot of that - but since I don’t use that, I wouldn’t know. But guess what - that’s Facebook too.
At present not being on Facebook is merely an annoyance in most circumstances but if at some point the choice is between being on whichever the dominant platform is or having no social intercourse at all other than with whichever poor sods you bump into in the flesh then there will need to be some sort of regulation/ oversight of their decision making processes.
We’re not there yet and may never get there but that doesn’t mean it’s not worth putting some thought into what the rules should be.
