Saying "but you may as well" gives the impression that you refuted the point the quote was making, but in reality you were refuting a point that, by your own admission, the quote was not making. That is a strawman.
Reading between the lines of a commercial is fine, and encouraged. Dismissing the point of the commercial entirely because of a semi-related tangent is not.
If you meant it differently (perhaps not to dismiss the quote's "argument" but instead to just bring up the privacy implications separately) that's great and I'll take your word for it (and even agree with it), I just found your original quote to be saying something different.
edit: I see that you are not the original poster of the comment. This comment was meant for that person, not you. Apologies.
Reading between the lines of marketing (or any text, really) is an important element of critical thinking. There's no rule that says I have to only talk about what your commercial wants me to talk about.
Are you really suggesting we should just uncritically nod along with whatever facile ideas are fed to us by an advert? <-- (Psst...this is actually a strawman)
