Does your reasoning apply to other companies? Coca-cola, for example, is very interested in building profiles and modifying behavior. I estimate they're much less sophisticated w/r/t building profiles (although if you think in terms of flavors, instead of demographics, perhaps not...) They are definitely very effective in terms of behavior modification. The product does significant harm. It also hijacks an evolutionary flaw (people like other people's feedback=FB, people like sweet things=CC).
Not the OP but I think it definitely does. What's the public health damage caused by disease epidemics like obesity and diabetes in the long term, tens if not hundreds of billions, even more?
It's time to bring the hammer down on advertisement and manipulation of people's behaviour. Imagine if the government would try to nudge people in the way these companies do, we'd never here the end of it and rightfully so.

(Not the OP) Personally, yes, it applies in full to all other companies. That said, marketing and advertising companies (which Facebook counts as) are the most egregious with this sort of thing.
