Re: ACTION-211 Draft text on how user agents must obtain consent to turn on a DNT signal

Seriously?

You're kidding right? DNT only requires you read the incoming header to
see if it's present. Now I have to do the browser UA sniff test and then
reject someone because even though the DNT flag is correct you don't like
that the OEM enabled it by default.

I can imagine Adobe adopting that on their Web site - Not.
