Existing regulations are a restriction on the freedom of service providers. That is undeniable. There many cases where we restrict freedoms for the greater good, but I don't like to pretend we are not doing so in those cases.
I'd also add that freedom is not the right to demand other people give you something you want. I wouldn't say that I've lost my freedoms if there are no good ISPs left after the regulatory change. Everyone involved can still either choose an existing provider or set up their own. We have monopoly/anti-trust laws when that ceases to be the case. Of course, this may not be the efficient path to a world that a huge majority of people want - which is why I slightly side with net neutrality.
