Having such freedom available is of no use if people won't make use of it. You assume a "nanny web" is about taking away these freedoms, when in fact it's about incentivizing people to actually utilize them.

I agree with you insofar as Mill's free market of ideas is the best remedy against bigotry and extremism, but you have the wrong idea about how to achieve that -- unregulated laissez-faire "freedom" on the web does not result in actual free discourse. On the contrary, that's just a recipe for a web overrun by all manner of adware, malware, spyware, propagation of unconscious self-censorship by means of universal targeted and mass surveillance, and straight-up disinformation ops and public opinion manipulation from hostile actors. How are you going to have sincere exchanges of ideas at scale over all that noise?
