One could apply the same logic to ISPs, after all. If you don't like Verizon's privacy policy you're free to switch to Comcast, or ATT. Oh - they all have the same privacy sapping policy? Too bad.
Certainly it should not be too much to ask that a "normal" non-technical internet user should feel free to roam the open internet without every click and view being tracked. I cannot expect to train my grandmother avoid google/facebook, use privacy badger and/or ublock and know what to do when her video doesn't load or play because privacy badger has blocked some adobe tracker....
This is hacker news. Let's not accept cringeworthy arguments that could have been proudly published by lobbyists for Facebook here. If this audience cannot scale higher what hope do we have for society at large? So yes, we should have regulations to limit what ISPs can track. And yes, those policies should apply to extremely large internet ecosystems as well.
