Because it's clear a single islander still leaves at D1 and that forces 2 islanders to leave D2 and such. The guru clearly changes the base case and superrationality doesn't change anything.
That's what I think it is. It's obvious to us that the proof by induction still applies, but for some reason Flewk is convinced that
a) Given a number of Blues, X, those Blues have some shared minimum knowledge that there is X-N blue islanders. Flewk believes that N=2, I think.
b) If the number that the Guru says is X-N or less, then no new information is given, and the islanders don't leave.
We all need to get on the same page though, because it seems that a lot of the replies in this thread are almost irrelevant to what Flewk is arguing. Which is why we have a half-dozen "Let me see if I can explain it better..." posts and nobody has been able to actually get anywhere.
