Well tbf, there is a regulator and there are price controls. They've been given license to extract wealth, but not as much as possible.
I do share your bitterness. Free-market fundamentalists have flogged assets for years, and the cost to the citizens is some future government's problem.
There are a few services best left in the public sector - e.g. defence, water, mail delivery.
When one government, for its own reasons, sells a service, intervention is required to return it to public hands. The cost of that intervention was created by the government that sold the service.
The intervention could be more or less problematic, but it isn't the problem.
