I 2nd the post which said "Just turn it off" but those folks will complain about having to pay extra for it being there. Well, if it also comes with TRUE ring USM , a better build than the 1.4 and sharper wide open then be happy for the improvements you CAN use because you can't please everyone all of the time yadda yadda yadda
Just to put this whole yes/no to IS discussion in perspective:
I haven't heard anybody complaining nowadays that a lens is AF and argue why pay for the AF mechanism if you can MF just fine???
IS is like AF, it may take a while for (almost) everyone to adopt it, but it's technological advancement and quite literally 'IS' the future
Of course not all lenses will become IS just like not all lenses are AF.
