You're arguing with a strawman, I never said it's impossible in principle. I said it isn't currently categorized as a utility, hence they are free to censor as they see fit.
It's entirely possible for the courts of the USA to deem it a utility, and it'd be interested to see the long term effects of such ruling.
The ruling would only apply to citizens of the USA, so it'd be very interesting to see how the companies in question implemented the changes to stay compliant.
It'd be an interesting case study, but it's impossible to speculate on its fallout until a clear plan has been drafted. I.e. It could potentially make it impossible for newcomers to create platforms, depending on the angle for such a regulation. Or it could make changes to the algorithm borderline impossible etc.
basically countless pitfalls and without a clear draft, nothing of value can be discussed
