Seems to me that you are writing about a completely different issue from
the one in the original post. In any case, you are not replying to my

So the situation we are discussing is one where some developers have
released software X under GPL and company C has chosen to use that
software and finds a bug in it. Why is it "harder (for the original
developers, I guess) to accept contributions (from company C)"? I really
do not understand this argument. This is the question I am asking Jon.

you are of course right, but these arguments concern the issue of what
license developers of open source software choose for their software.
If the goal is to maximize the users of a particular piece of software,
then I agree that perhaps a BSD style license is a better choice than
But this is not what we are discussing here: we are discussing that a
particular company has *chosen* to use some open source software and why
the fact that this software comes with a GPL license makes the situation
worse ("a one-way street" in the words of the original post) in terms of
user contributions to it than a software released under a BSD style
license. I do not understand the difference (if any).
