You're right, there definitely is (and it's obviously not a given that the service degradation would be attributable), but I think the product companies that are on the receiving end of the complaints will probably start putting money into correcting the problem (or at least rectifying public opinion) once people think the products are the problem.

Google is going to be pissed if their new wifi router doesn't work properly despite millions spent on testing, just because Verizon is screwing things up for everyone.
