I disagree -- I don't think that the FSF considers the GPL a "poor
fit" for libraries.  Quite the opposite (see [1]).  They just
recognized that in certain situations, some people would prefer
something like the LGPL, and I guess that they wanted to give them the
choice.  But the GPL is still the option they recommend, even for
libraries.

[1] http://www.gnu.org/licenses/why-not-lgpl.html

Regarding the broader issue (of how people license their libraries): I
think this is an optimization problem where people have heterogeneous
objective functions, and thus trying to convince people to pick
another license is not always a worthwhile.

It is possible that someone using a GPL/LGPL/LLGPL/BSD/MIT/... license
is perfectly aware of the advantages and disadvantages, it is just that
they decided to make a different choice.  In which case, threads like these 
are unlikely to be fruitful.
