I agree that this process happens. That doesn't mean you shouldn't take advantage when situation 1 is occurring. It means you should evaluate periodically if you are still in a situation 1 for these types of things. Amazon prime and Netflix used to be situation 1s. They aren't anymore. If you're willing to give them up I don't see the problem.
There are network effects help the companies from phase 1 to phase 2.
Ultimately there's an inertia in human decision making that means we almost always stick around longer than we should when we are being taken advantage of.
I would say that it's not worth the hassle of creating the hassle of escaping.
