I don't think that you're being overzealous. Far from that - even the phrasing rubs me the wrong way; it conveys "you're something fooling itself that it has a choice. You don't - you aren't a rational human being, you're a user. Do as you're being ordered to. The continued pestering adds "You'll be bossed around until you learn to obey." to the insult.
On a lighter side I agree with Grouchy that you have options. I think that we should start giving those companies the middle finger. And frankly I think that we're better off doing so for other reasons - the data vultures love this sort of "non-confrontational on surface, but bossy upon analysis" discourse.
