While I tend to lean towards libertarian the reality is that "someone will fill the market gap and customers will leave" is largely a myth. Even without lock in or other reasons the market tends to be rather shallow with only a few choices. Maybe HP is the instigator but it largely signals to their competitors that "hey you can be abusive too". This creates a casual follow-the-leader collusion then everywhere sucks and there's nowhere to go anyway so why leave.
