Incorrect GPL interpretation
You should purchase ActiveWidgets commercial license for all types of commercial software or internal systems development except for the work released to the general public as an open source.
That is incorrect, or at least misleading. I'm sure its not intentional (perhaps you don't understand the GPL). Under the GPL, a commercial company can create internal projects using GPL source code without contributing their changes back to the source. As long as the company does not distribute their software to anyone outside the company, they are in full compliance with the GPL.
As it stands, someone can use your product legally for a internal software without impact, without purchasing your alternative license. If that's not what you want, then you should use a different license. But misrepresenting the GPL misleads people into misunderstanding the license. That does the GPL a great disservice.
