Here's the thing, though.. they can't just up and leave for some other pool. There was a poll among their members, and those members overwhelmingly decided that switching to P2Pool is what should be done. Presume that can't be done - at least for now - guess what the next most popular option in that poll was? To stay where they were, at Ghash.io . If they up and switched to some other pool, they would effectively be going against their poll - against people that basically pay them to act in those people's best interest and the only deciding voice they had on that was through that poll.
Now... I will certainly say that they probably should have done their homework first (though for all I know problems only pop up when at scale), or at least have had the poll give a fallback option in case the first choice didn't work out technically, ideologically, or logistically (say the pool shuts down for whatever reason)
But with the situation they're in, they can only do two things: 1. Work on getting things up and running on P2Pool asap (knowing there's some pressure on them to do so), or 2. Put up another poll to select a different pool yet again (and accept the chuckles and headshakes that will go with that display).
Given additionally that Ghash.io's share dropped quite a bit, option 1 is the logical choice.
At least, that's my point of view - they can always jump to some other pool anyway and tell their unit holders to deal with it
