Doesn’t matter anyhow.
The major ISP’s already throttle bandwith to certain IP addresses.
Google.
Amazon.
Spectrum.
Comcast.
Pick one. All of them do it. They can, because they built and own the infrastructure that your internet runs on.
These are not public utilities. If they want to censor you and your website, for any reason, or no reason at all, they can, and will.
But did the FCC just sent a message to those companies.
Are you contending that the throttling occurs due to ISP objections to ideology, or because of ISP objections to sites that for example are providers of streaming HD video, or both?
Can you track your contention?
