CalEvans Hmmmm...modx seems to have a corner on the clue market http://thrash.me/tech-and-modx/modx...

(Referencing the MODx CMS of course.)

In the linked blog post, Ryan Thrash, Chief Executive Officer of MODx writes that, although they feel they would be within their rights to force extension authors to use the GPL, they have no plans to at this time.

How reassuring. Not.

Project leaders come and go. As they do, forces for and against strict adherence to the license (the GPL, in MODx's case) will ebb and flow. The sentiment at Joomla! was highest 3-4 years ago. The WordPress community has been rocked by this debate in the last few weeks. And apparently MODx has not gone through one of those peaks in a while.

They may never, I don't know. But I do know if I were a non-GPL component developer for any GPL software, I should be aware that my business is never immune from threats over license non-compliance. (Threats are possible whether or not I have done anything actually in violation of the license, as discussed at my previous post on "Derivative Works".)

Of course, personally, I would never be a non-GPL component developer for GPL software ;-)
