I think you may be confusing content with the signal itself. This is about ISPs controlling content indirectly by throttling the signal via prioritizing content or altering transmission rate depending on content. When Facebook or Google block something they are controlling the content directly via their servers and not affecting the ISP transmission rate or priority.This is a totally bogus issue masked by an appealing name, "Net Neutrality." Now the democrats are claiming the internet was a "public utility" but now is controlled by monopolists, thanks to the evil Trump.
If the internet was a public utility, how were monopolists like Google, FB, Twitter etc able to block websites or posters whose politics they disagreed with? If that was an example of "neutrality," then I'm all for changing the rules. I actually think internet monopolists should be treated more or less as public utilities, eg required to offer their platforms to anyone not engaged in law breaking. Allowing a small group of billionaire progs in silicon valley to determine what is acceptable internet discourse is the antithesis of "neutrality" yet that is what we got under Obama.
The internet operators like VZ and T should be prohibited from viewpoint discrimination as well. Repealing net neutrality has nothing to do with that however. It is just a battle over who pays the cost for streaming services between two rival groups of mega-corps. IOW the spoils of politics.
This is about preserving equal access to all content providers to the internet. Some of us take the position, I am one of them, that the ISPs should be restricted to providing the signal and not be allowed, indirectly*, to charge differently depending on content. And the content providers themselves should determine content with all content providers being entitled to equal treatment by the respective ISPs.

* the ISPs will say that all content providers will still have access, but if they can transmit different content at different rates as they see fit, they will indirectly control content by making it impractical to view certain content because of a slow transmission rate.
