Indeed, collusions are part of the thing for me (wouldn't forbidding them be a regulation, which opposes free market?).

I can understand that someone would want a free market but forbid collusions though.

But are collusions a cause for an ISP raising there prices when there are no competitors?

I think the argument is that collusions are one of a small number of reasons there aren't competitors. I.e., the act of raising prices in the absence of competition is all fine and dandy from a quasi-free market perspective, but there should be more competition.

This would sharply contrast with me being fine with a service being provided without competition as long as it is good (and then yes, you probably need it to be public or heavily regulated)
