Well, this is bizarre. Assuming this is true--which is a lot to assume--this would seem to indicate that the miners don't understand the way their power works. Say they switch off to mining Classic_ and trigger the activation; give it a month or whatever, and they start popping out their 2MB blocks,
which are then rejected by all non-Classic_ nodes on the network. Unless they convince the rest of the system to switch to an implementation compatible with their consensus rule change, no one else will accept their blocks as valid; all they'll have accomplished is that they've forked themselves onto an altcoin.
Not sure why mining pools would even really care all that much about 2MB... What do they think it would do for them? Make their operating costs a bit higher? If they're hoping to see increased adoption cause a price boost, capacity (especially in small amounts) seems like the wrong approach--it's not like 2MB blocks make Bitcoin easier to use, increase its privacy, increase merchant acceptance, or make it possible to buy milk at the grocery store without waiting 10 minutes for a confirmation
But hopefully this is just some bullshit scare and doesn't have any credibility. I'd like to hope that miners are smart enough to not bite the hand that feeds them in an absurd attempt to completely sink themselves.
