I have never heard of anything like that happening in the US before 2015. Could you give me some examples of this happening?
I've heard about Google and Facebook and Twitter blocking sites and content that they consider inacceptable, such as Russian media outlets associated with Russian government. I have also heard about some Nazi sites recently being essentially booted from the Internet by companies no longer wishing to be associated with such sites. All this happened while 2015 regulations were still in place, so apparently NN, at least as far as 2015 regulations go, is no barrier to this.
However, I have never heard about ISP blocking access to an abortion clinic (excepting parental control, etc. setups of course, which are usually done in more localized manner).

How? Any why anybody, at a time where one can lose his job just for questioning HR diversity policies, and be booted from air for having the same name as a Confederate general, would be crazy enough to do such an outrageously racist thing, even if this were possible (which it almost certainly won't be)?
> While I think that's an unlikely outcome, it would be devastating to free speech, equality, and diversity.
If it's unlikely outcome, why Canadian politicians talk about it so much and do not talk about more likely things? Rhetorical questions, of course, I know they are just blowing hot air and duckspeaking.
