You got an extremely good point here. At least it shows why this way of
doing is not "moral", but, looking at the GPL text, there is nothing
stating any obligation to "pay" in any manner (money or contributions)
to use and/or modify GPLed softwares.
Just to illustrate my point, in the case of an webserver, if the
webmaster patch the code of his own webserver to provides his customers
with a new service. Has he the obligation to redistribute this code ?
Namely, his patched webserver will never get distributed. The onlyCorrect, so only the licence on the html files (if any) will matter.
interaction between the customers and his webserver will be through
exchanges of HTML files.
Therefore, it would be nice from the webmaster to contribute with hisIndeed, because he didn't distribute the webserver binary
patch, but I do think that it is his own choice to do so.
Note: Originally, the redistribution of the code was mainly to avoidThe point is forced open source. If you can do business using
customers or companies to get stuck with a "no more maintained"
binaries. In the case we are looking now, as the hardware is not
belonging to the customers, there is no such risk. So the protection
seems to be against something else... but what ?
Not getting stuck is one thing. Not needing to reinvent the wheelThere have at least been cases where companies were selling
linux-powered products, and were told that they had to
provide the sources. I don't know if any of them bothered
going to court, simply making the source available (on a cd
or webserver) is so much cheaper than that.
LinkSys is an example. But the customers were owning the machine with
everything in it (including the OS). Again, the clause on distributing
the sources help to not get stuck with a piece of hardware that you own
with no possibility of upgrade (remembers me the famous story of RMS and
the laser printer).
Well, then they need to secure their DSLAM setup. If it is at allAn interesting thing about the GPL is that it talks about
"distributing copies", not about "selling or otherwise changing ownership".
"Distributing" a linux kernel embedded in a product owned by the
company doesn't change that. Where the binary kernel go, the
source should go too (if requested).
Fortunately, this licencing term is so easy to satisfy that it'd be silly
to try to fight it. Stick the source on a webserver somewhere. Provide
the URL in the accompagnying paper (or a README file if appropriate.)
If distributing cd's, consider sticking a tarball there.
Well, I'm really sorry to play the Devil Advocate once time more, but as
far as I know all these DSL companies have big secrets because of
weaknesses in their security. Being hacked at the Internet level is one
thing, being hacked at the DSLAM level means a lot. Try to imagine if
anybody could upload to you his own modified kernel, this means that you
can tape all the internet traffic, all the phone calls, all the TV
programs that you are looking at, and also probably having an easy way
in to your local network (wired and wifi).
