I feel bad for them too BUT SE can only do so much - the gave them their own "native" datacenter 2 years ago...if they chose not to move then that was their choice and this was a future risk they were taking. Montreal was more "central" for EU/NA when there was no EU datacenter. I bet the thinking was:
ARR: EU/NA datacenter in "central" location aka Montreal
HW: EU datacenter created to better accommodate EU players, NA datacenter stays put for now to see how it works out
SB: NA datacenter moved to west coast of US which is more "central" for NA+NZ/AUS players
I do think people should be able to do a one time free transfer though with all their gil/items (but not FC, houses, etc unfortunately) to the EU datacenter.
