(via Do Not Track Is An Opportunity, Not a Threat | John Battelle’s Search Blog) This is a mockup — for now anyway. But speaking personally, I think it would be fair enough; albeit with the addition of a 3rd option “click to pay (eg: 2$) for a months access to ad-free version” or similar.
First off, to emphasize again: This is a mockup, not real. But it’s rare to see Microsoft ahead of the curve on something like “Do Not Track,” which will be turned on by default on IE10. The solution for sites which could suffer from this type of change is to be upfront about it. Or, you know, to change up their model a little. Either way, let’s not do more stuff like this.
