Well, GPL software can link non-GPL libraries (if the library does allow that,
and ECW does it). This is exactly the reason why GRASS (GPL) can use GDAL (MIT)
without problems. The issue I see is that so many softwares out there are not GPL 
(but free anyway) and so cannot link ECW. I also find 'similar to GPL
and at no charge' is a quite rough definition of the spirit of FOSS. In
a few words, ECW almost-free license needs major revisions...
