This all sounds crazy to me. Maybe I just don't get it

It's gonna be the pool that ends up censoring the transactions surely? Individual miners, or even large farms of miners aren't going to give a fuck about what transactions go in where, they just want the maximum reward for spending all that money on equipment and electricity right?

If it was up to the invdividual miners, say if there are 1000 miners 50% of them could not accept a midgetpornmeme transaction and 50% could, or even if there is one pool that doesn't accept a particular transcation but another 4 pools do, I mean whats changed?

So the pools going to end up doing it, but will it make any difference, and if not why bother doing it unless its just to promote your own pool/code/software and cut some extra profit somewhere on the side for yourself as a company.
