"If a government makes it technically illegal to take non-harmful actions in order to refuse service to someone who will not pay for that service"
There's nothing to stop any server paywalling their site. That's not the point here.
And the user viewing ads is not paying. Someone else is paying, the advertiser of whatever product or service is being advertised; and oddly enough they're quite likely paying good money to piss off the visitor who will then be making a mental note never to spend their own good money on that product or service.
