Hello Konstantin,
I think "Bestunar" do make the two wrong things.
One, they put the copyright without your permission. 
But I doute that you copy and paste the Montage Technology's reference code and why not put Montage copyright?
Two, they write the code based on the ds3000.c file which you created, even they enhance and fix some bugs.

They build the products based on Montage Technology advanced M88DS3103 chip, which is totally a new chip different from old ds3000.
And they are the first company to adopt this new chip on the Satellite DVB-S2 tuner cards.
They do the right thing now that create a new file named m88ds3103.c for the new chip in linux media tree.

hello Andreas,
i've checked the Linux drivers for the card you referred to and
whoever made it is breaking all the rules claiming copyright over the
whole driver adding at the beginning:
"Copyright (C) 2010 Bestunar Inc."
when they just patched the driver very slightly adding only new
initialization values - if they wish they can claim copyright only
over those small changes (even they are just number constants provided
by the chip maker). in any case that's ridiculous, because i made that
driver and the copyright notice is:
http://git.linuxtv.org/media_tree.git/blob/61c4f2c81c61f73549928dfd9f3e8f26aa36a8cf:/drivers/media/dvb/frontends/ds3000.c
    Montage Technology DS3000/TS2020 - DVBS/S2 Demodulator/Tuner driver
    Copyright (C) 2009 Konstantin Dimitrov <kosio.dimitrov@gmail.com>
    Copyright (C) 2009 TurboSight.com
and i strongly opposed that copyright massage can be changed in the
way like they did especially over the changes they made.
also, the whole 'ds3000' driver, even it's licensed under GPL, was
submitted to the Linux kernel without my formal permission that to be
done, i.e. you can think for that as it was leaked to the Linux kernel
from third-parties and not the driver author and copyright-holder.
so, it seems to me "Bestunar Inc" is some obscure Chinese company most
probably cloning hardware rather than spent any time doing
development, which or course also don't honor the work put in
development of open-source driver for the chips they're using and try
very hard to make it look like they did it or that they did something
more significant than what they actually did. i'm sure you can
understand my position and my opinion that such companies shouldn't be
supported in any possible way.
best regards,
konstantin
