There has always been a sizable minority of non-GPL open-source software, such as the BSD community. Not to mention groups like X11, zlib, Perl, and Python who invent their own license for some damned reason.
I haven't noticed any particular recent changes away from the GPL; for example, all of the major DVCS tools (Bazaar, Darcs, Git, Mercurial) use the GPL.
For what it's worth, I prefer to avoid non-GPL software. jQuery and Firefox are at least dual-licensed, so I don't mind using them, but I prefer to avoid Chromium (and especially Chrome) unless necessary.
