This would trivially fail as even if the top 1000 sites were to agree to leave Google, each one would *individually* have interest in betraying the plot and staying. I.e. the bribe price shall not be the *average* but the rational price of betrayal, which is much higher, and actually increases with the number of participants.

Technical impossibility is a non-argument. Strip out perhaps only the most visible things (like the executable). Make it a free, largely advertised download. Just as Opera/Firefox/Chrome. It *does* matter a lot because OEM/developpers/whoever will *not* assume that IE exists by default. However easy it is for it to be installed back. The whole point is that the *user* has to *explicitely choose* MSIE over the competition. That makes a whole lot of difference. Obviously you should not let OEM choose - MS has too much leverage there, as the WMP fiasco has proven.
