I thought you might have meant that a statute could not affect an existing contract. I had never heard of that before, but governments sometimes compensate people who suffer losses because of legislative action, so there might be something to it.
I don't want the government to interfere much at all in private affairs, and I don't think "there should be a law against" everything I don't like. I am not sure in this case, but conspiracies to prevent third parties (tenants and ISPs) from conducting business are pernicious. I would never enter into such an agreement myself.
I do. The current situation massively fucks citizens and our current Internet situation is sad joke in most of the country because of it, and the Internet is important infrastructure. Of course this is a matter the government should deal with.
