I beg to differ. Let's take a possible scenario. Let's say that my company
has a complex software product that sells for $1M a piece. And let's also
say that I need some encryption for the product. I find an encryption
library that is free and is GPL licensed. What happens if I use it?
Correct me if I'm wrong in any part (and I genuinely admit that I may be
wrong). I have to release my entire product under a GPL license and I have
to publish the entire code (I assume that the use of the encryption library
is not isolated to only one part of the product). Would my company want to
do something like that? I don't think so. Sure, we are still entitled to
try to sell the product but who would pay $1M when with a little effort they
can put the entire product together from the code and any support that we
could sell is never going to be worth the money we are asking for?
Red Hat can make money from selling their Linux distribution, but apart from
companies that have deeper pockets and for whom getting the support and
warranties that Red Hat offers are worth a relatively small fee, how many
small consumers buy the commercial distribution when they can just download
the same thing for free? No wonder that Red Hat also sells things like mugs
and T-shirts.
So getting back to my scenario, leaving theory and "orthogonality" aside,
practical reasons will stop many companies from using GPL licensed code in a
commercial product. I think that constitutes interference.
