Is Sveasoft Violating the GPL?

Ron Harwood writes "First, Linksys was violating the GPL by not releasing their source for their Linux implementation on the WRT54G wireless router and WAP54G access point. When this was rectified, third party firmware started showing up. Well, now it looks like Sveasoft (one of the third party developers) has decided to restrict access to their modified source code to subscribers - that also will need to pay $49 for a CD rather than being able to download it." The thread summary at DSLReports only makes it clear that this is all very complicated.
