I know you don't really understand the GPL but perhaps reading the officlal GNU/GPL site will clear things up.

The developers who told you they are unhappy are simply trying to hoodwink you. They're trying to have their cake and eat it too. They are releasing commercial software and promoting it as being GPL but when someone actually exercises their rights under the GPL they seem to want to cry about it.

In some cases it might be that they just don't fully understand the ramifications of GPL licensing or perhaps they just want to benefit from the promotion of their product as being GPL while never intending to honor the license. In any case, they are the ones in the wrong because legally GPL software once released must remain GPL in the form in which it was released.
