I'm not a lawyer so I never speak from a "legal" standpoint, even when I'm
talking about licenses.  The pain is from a technical standpoint.  If I make
a modification that I think others would also enjoy, I had better hope the
project team accepts it into the core; otherwise it will be not only onerous
for me to maintain (just ask Christian Tismer), but also onerous for the end
user to build from source.  (The same end user who might be quite
comfortable following instructions that say "type configure; then type make;
then type make install", might be deeply mistified by tools like diff and

What this constraint does accomplish is that if deep philosophical
differences leave one with no choice but to fork (q.v. XEmacs), it makes it
much harder for the forkers to succeed in taking mindshare away from the
original developers.  But if the original developer abandons the project, it
also makes it more difficult for the code to take on a life of its own, and
find another owner to care for it.

My dislike of QPL does not apply to QT itself, since Troll Tech is kind
enough to make that available under GPL as well.
