I deleted my earlier answer, as, indeed, I wrote it after flipping with rage from the whole story. My apologies. (I know Dutch universities system quite well, as I worked there for over 10 years).
The story, however, smells so badly that it's really hard to keep silent about it.
E.g. try to explain the fact that there are several people in the Department (but outside of Geometry Group) that work... yes, in topology (symplectic topology, Floer homology, etc). E.g. they published MR2461255 (2009k:53225), this is in 53D35 (Global theory of symplectic and contact manifolds). Well, you can argue it's not "pure" topology, but rather its applications to differential geometry---still IMHO close enough.
Now the administration will terminate topologists from another group. I think the call to "save pure maths at VU" would not make too much sense, right?
PS. It seems that the call to "reform the administrative system at VU to make it more transparent and fair" would be more at place.
Well, I signed the following petition, anyway: http://www.gopetition.com/petitions/save-pure-mathematics-at-the-vu-university-amsterdam/sign.html
