But the examples given aren't issues with individual customers at all, or even groups of customers. They're issues with types of Internet traffic. You seem to be assuming that the ISPs wouldn't ever do that again, or that they wouldn't ever do it to a type of traffic you're interested in. I think that confidence is misplaced.
I'm saying the threat to the internet from any (IMO) minor traffic management practices by ISP's is much less than the potential threat to internet freedom from government via the FCC.
Throughout recorded human history, it has been GOVERNMENT that fears free speech, not private enterprise. The Holy Roman Church and the Gutenberg Bible. The King of England's licensing of printers. The FCC throttling of broadcast via the Fairness Doctrine.
To expect all of a sudden that the FCC would become a benign master of the World Wide Web does not square with logic or history.
Do some research on early radio history and see where the Marxists almost succeeded in turning commercial radio into a 1930 version of NPR.
