I disagree absolutely.

Nor are they likely to be, for reasons explained below.

(Minor point: Linux distro vendors sell such libraries every day. I'll
assume you meant "incorporate a library with a GPL license into a
proprietary product.")

Not so. If the GPL were declared void, the defendant would have no leg to
stand on at all, because without the GPL, anyone copying or distributing
the software in any way at all is exposed to the full force of naked
copyright law and is clearly an infringer (and subject, in the U.S.,
to fines of up to US$50,000 per infringing act). The last thing such a
defendant wants to do is bring a direct challenge to the GPL's validity,
which is *why* even the few cases of actual criminal infringement have,
according to the FSF, settled fast.

In the case of simple permissive licenses, there is very little
incentive for anyone to sue.

> If you want to optimize your library for adoption (very important)

It's important if that's what's most important to you. Other people
have other values than "disseminate my code as widely as possible".
In particular, people who use the GPL or LGPL generally don't think
that way, or they would be using a permissive license.

There will always be particular licenses that people refuse to use out
of fear. I suspect (but can't prove, of course), that most such people
fear *all* free software however licensed.

Hard luck for him and his employers. They always have the alternative
of redoing it themselves, probably not as well. It's a business
decision whether evaluating the license is cheaper or more expensive
than reimplementing XOM. Also, as Michael Kay says, people can pay
ERH for exceptions.

Google for "license of Guile" instead.
