Earlier quoted context omitted.
I was just in Lima, Peru. This is what you see if you're on Facebook on someone's phone (I was tethering), and click a link that takes you outside of Facebook: https://s22.postimg.org/lilkrmo4x/Screen_Shot_2017-06-21_at_... What do you think your chances of competing against Facebook, or Facebook-based businesses, are, when clients see this before accessing your site?
Any viable competitor will necessarily have the resources to strike a similar deal. I think your argument boils down to "is unfair that Facebook has more resources than a competing startup", which is no truer without NN (in my mind, anyway).
It's a huge, huge fallacy to claim "this thing would happen regardless, so who cares how difficult we make it for it to happen". Your mind is wrong.
I'm proud of India for rejecting Zuckerberg's ploy, and I wish Peru was wise enough to do the same.
