Your ISP isn't a search engine. It's also regulated more like a utility, unlike Google. If your ISP started black-holing IP addresses for reason of the content they carried, there would be Congressional action (if the FCC didn't get there first).
Because of network effects that turns out to be a lot weaker protection against much more powerful companies.
Edit: Perhaps network effect is the wrong term - but it’s a bit like saying if you don’t like guns don’t buy a gun - that doesn’t really limit the negative impacts from guns...
