The people responsible show a distinct lack of understanding when it comes to consent.

Silicon Valley has no concept of consent and boundaries. If computing was a night club, "Silicon Valley" is the guy who goes up to every woman saying "Want to dance? [Yes or Maybe Later]?"

I don't think you carried on the analogy far enough.

>Want to dance? [Yes or Maybe Later]?, also drink this [Yes]"

A better analogy would be slipping something into her drink whilst handing her a 12-page stapled terms of service agreement in which she unknowingly gives full consent.
