I had some trouble with the closed source fritz card dsl 2.0 driver
e.g. which suffers from a race on recent kernels (I guess Karsten Keil
informed you meanwhile). This should have been tracked down easier and
earlier (last worked on 2.6.8) if your drivers were part of the kernel
or at least taking part in the community.

I really like your hardware, but I dislike such license models.

I tell you my opinion but I will not accept any discussion???

Well, I guess it's not your own decision that AVM is still stuck on
closed Linux drivers, your management may it's own ideas about it as
well. But who else should try to change this than the "engineer at the
front"? This is how many success stories of companies in the open
source domain took off.

I don't know your market, so I may neglect that you have to protect IP
very strictly from nosy competitors. But what part of this IP really
has to be inside the kernel driver? Can you explain this to the Linux
community? This may help a bit to understand your issues with free
drivers.
