Nobody's spraypainting on Facebook's house here. They're using it as it was intended: as a method of one-to-many communication for messages which contain nothing illegal.
The public thrives on the basis of such "dumb carriers" as the internet itself.
I can forsee either regulation or self imposed ubiquitous clear CATEGORIES of rights for speech from users on sites and applications similar to software licensing.
You would have a Facebook under the <Proprietary license> A Facebook under the <Academic Free License> A Facebook under the <GNU General Public License> A Facebook under the <MIT License>
either under a parent company or as distinct entity. Some are free, some cost money, some may receive tax benefit or government subsidy, all according to how they align with net neutrality regulations, are staffed and moderated.
Is there free access to anyone to do same?
What ove a telephone line over which only specific messages may be sent?
What of a wireless earpiece connection over which only designated messages may be sent, or to which only designated devices may connect?
Can you name any "line", at all, in any sort of dilemma? Obviously it's okay for you to gently tip on the shoulder of someone blocking your way in certain situations, but in other's it's rude, not to mention "physically interacting" with them with more force and different intentions. Where do you draw "THE LINE"? Between being polite and being impolite, as well as being impolite and assault? How would you write the rule book to determine it in any situation for a minimum wage Facebook employee or algorithm so they wouldn't have to apply any of their own judgement? And just because you couldn't, just because nobody including God could, would you still refrain from judging even extreme cases with some certainty?
So? You know, maybe at least try to answer that, as a thought experiment and learning experience for yourself.
I would expect not, but that means there's a line somewhere. Where is it?
