Rest assured, many of the brightest minds are aware of Facebook's business models and incentives, and many of them predicted the current situation and rejected the company many years ago.
...and promptly took a job at a Google? Sorry, but someone is working for these companies, and they’re clearly bright enough to make the necessary tools. I’m sure some extremely bright and principled people refuse to work with anything like an Orwellian nightmare, but enough do to make up the difference.
Do you think that the code that tracks loggedin and not loggedin users differs much? I assume is the same tracking code, but if you are not loggedin FB and Google will give you an unique ID but after that they collect same data, they will need to add some code for merging data if they find that 2 different IDs are the same person.
I am not defending FB, my point is that you do not need an army of geniuses to extend the tracking to everyone.
