> But when you can enough of them pointing in the same direction, it creates the chilling effect-- a business that's technically legal but can't get the services they need. It basically creates am unspoken private regulation well beyond the actual law of the state.

Yes, but this is how the free market works. That my $.25 artisanal dog cupcake business can't get the services it needs at the price I can afford doesn't raise complaints.

But when we replace dog cupcakes with Nazi chat rooms, suddenly we need the government to step in and subsidize a business which the market has shown is not worth it. In economic terms, the "distaste" of a client is an externality, and there is an increase in price associated with that externality. If the company can't afford it that's just the market at work. So the government providing a platform like this is just the government subsidizing business with negative externalities that the free market was correct tly pricing. It's like subsidies for strip mining or fracking or rhino poaching. But this is something you support in this case.

It's odd to me.

> I tend to think the answer might be non-profit or state-run "service providers of last resort" -- charter-bound to provide service for any legal purpose, no matter how distasteful.

And what if my distateful venture needs redis or windows 10 or a spanner like distributed database, or whatever other service your unflashy system doesn't provide?

Then either I can't get off the ground anyway, or you require that the government service maintain feature parity with all the others, neither of which seems viable.
