Hehe, you seem to miss the importance of the stuff Jeff posted. This is
not a Drupal issue. It is an issue for all GPLed CMSes using PHP, Perl,
So your companies are then welcome to develop their own CMSes or buy one
that already exists.

The world got a solid, very scalable, very versatile operating system.
I've been using Linux before IBM "endorsed" it and I don't think big
blue's engagement did help /that/ much.

I think the community could do fine without IBM. Far better than IBM
without the community, at least.

No. But who'd care?

This isn't a question of yes or no. This is a question of "how". XML-RPC
and similar stuff is still allowed.
> I am all for a GPL-like license for the core, but I believe the long term interest of the Drupal project is best served by ensuring that third party modules can be developed with their authors choosing the license that is best for them much like developing an app that happens to run on an operating system.
Nope, sorry. Drupal has a license. And what would be using a license at
all if we wouldn't stick by its terms? Even if we (including myself)
interpreted these terms slightly different.
> Let's make sure that the ability to build third party modules under any license stays that way.
This ability has never existed. It has been a long standing agreement
(or at least nobody dared to challenge this position of mine) that
modules have to be GPLed. What is "new" or rather "was unknown" so far
is that intergrating third party non-GPL software through bridge modules
is problematic too.
