They are historical examples, which is all that is necessary.
I don't agree. Businesses and customers have honest disagreements every single day and usually they are resolved without government involvement. Isolated examples of these disagreements do not a pattern make. Such a 'pattern or practice' might require government intervention, but to date it just ain't happening.
I've had problems with my ISP over the years, but I pick up the phone and we work it out. I'm a good customer that pays the bills on time and they respond.
But to bring in a government agency with a history of censorship (see 'Fairness Doctrine') and put them in charge because of something that might happen in the future just not jive with libertarian/conservative dogma.
