I have my doubts whether a significant proportion of users would go to the effort.  It's difficult enough to convince many of them to use SPV over webwallets and exchanges, so they at least have control over their private keys.  Running a full node is also tricky in that not all users will have sufficient resources in terms of bandwidth.  There's a "path of least resistance" argument to be made.  Even if the average user did feel as strongly about this "attack" as you (and I'm not entirely convinced of that either), it's probable that people will choose convenience over politics.  

If people really do care, I suppose they'll find a way, but given what tends to be generally accepted about human nature, apathy and laziness should never be underestimated.



Then maybe stop relying on all these miners that you suddenly find yourself disagreeing with.  One could argue that if you really want to be in full and total control of your bitcoin destiny, you should grab yourself some mining gear and actually help build upon your preferred chain.
