The public/private divide is a well-known conundrum. And the analogy I gave is a practical example of that, one that has actually faced several nations. I note you've offered no basis for it being 'dishonest', either, which is unfair. Be careful before making statements like that.

The point is, you look at the substance of what is being done or controlled, not the status of the actor as a private or public entity. That is what the analogy is used to explain.

The substance of what is being done, here, is regulation of communication between individuals over a communication platform. Downplaying it as 'not hosting public content' is inaccurate or at least of no moment. What's public content mean anyway?

If a significant amount of private communication goes through privately owned channels, it is reasonable that the private companies operating those channels respect democratic norms. It's unreasonable to dismiss any criticism as 'they are a private company', as that's beside the point.
