That's a pretty defeatist take. Surely if you pay for a service you should expect the provider to be making good faith efforts to provide the same quality of service over time? Natural degradation would be fine, but purposefully sandbagging the service so it gets worse because cheaper is unacceptable.

That we have become numb to the point that we collectively accept such poor behavior on the part of vendors in concrete cases does not make the behavior acceptable in general.
