There's no necessary connection, though. Many libraries are released
The FSF is not the only copyright holder releasing works under the GPL,
as you know, so the FSF's policy on which licenses to use is not really
For that reason, I'm glad the FSF re-named the LGPL to reduce the
implication that discourages the GPL for libraries.

Yes. And that's a good reason to, in some cases, use the GPL for a
library. So perhaps we should be less surprised at the suggestion that
people do use the GPL for libraries.

To sympathise with Eugen's querent for a moment: it seems more likely to
me that they are concerned because they *don't know* whether they are
doing something wrong, because they don't understand the license (yet?).

Sadly, there are many who, presented with those options, will take the
unspoken option: to change nothing and continue to stick to a non-free
license and to avoid benefiting from the GPLed code.
I suspect Eugen wants to give an answer that is both true *and*
reassuring, to encourage the querent to make their software more free.
Perhaps I'm projecting too much of my own motives, though.
Talking to a lawyer about a question is difficult to suggest without
seeming to imply “don't bother me with that question”, which will tend
to discourage use of GPLed software. I would love for it to be

That may be a more diplomatic tack to try. Thank you.
