If anyone from GPL-violations is reading this - please, PLEASE do not follow your usual peaceful approach to GPL enforcement with AVM. In my opinion they seem to think it is appropriate to use the full force of the law against freedom. This possible violation is not a minor technicality, and it is not accidential.
Further, I found the information on the GPL on their website to be extremely confusing. It started by first stating the usual "all rights reserved", and only then (much further down) mentioning that all rights are not in fact reserved. I have previously contacted them about this and about the source code, and whilst they replied with a link to sources they did not respond about the my confusion with their site.
Enough is enough. If they want to repeatedly kick us in the face they do not deserve leniency, but the full force of the law. On By this I mean, assuming a case is won in court, and if I were a kernel copyright holder, I would not reinstate the license. Ever.
Needless to say, nobody I know will be buying anymore AVM hardware. Which is sad, because for the past 15 years I've been singing their praises, and whenever possible chose their products (they were the only ones who made reliably working ISDN cards, and I stuck with them until I found out about this) :(
They even seem to imply that Welte is shady/dodgy/untrustworthy in the German version of their press release on this, although their translator is rather incompetent and translated "seriös" to "serious", so it doesn't show up as bad in the English version.
