Re-licensing code to a compatible license is pretty much an exception. What
license can you re-license GPLv2 code to?
I think we've pretty much learned with experience that having to replace code to
re-license it is something that should be avoided at all costs. Unless you
assume that any contribution to your project will always be trivial and
replaceable, I think it's been pretty much a given that a CLA is necessary.

Huh? Once you distribute it without the source, it's pretty much proprietary.

So you agree with me that if you don't want your code to be distributed as
proprietary software, you shouldn't be contributing to BSD or GPL-with-CLA software?

Because big successful projects such as MySQL and Qt have _proven_ that selling
GPL exceptions is a valid model that advances the quality of open source software.
Honestly, I wish more software was like that.
I want the _default_ license when people write software to allow access to
source code. I want every single application I run on my Android phone to come
with source code. The only way to achieve that is to stop trying to prevent
developers from having a revenue stream with their creation.
For example, why isn't the Ghostscript model good enough for open source
enthusiasts? I'd gladly give a timed GPL-exception in order to get high quality
software that isn't developed in a basement, or with VC money. I'd gladly accept
that a certain piece of software is used in some proprietary product as long as
a contract is in place that assures me that every single improvement makes its
way to the GPL version.
As long as people criticize models that allow developers to invest money in an
open source software project without being able to monetize their investment,
we'll always live in a world where open source software is the exception rather
than the norm. That is not why I have spent a large part of my life dedicated to
open source software. I am of the opinion that free licensing is superior, but
every time someone tries to come up with a business model that allows developers
to actually get paid to develop it, it gets rejected by the very same community
who want to see it thrive.

Sorry, but I fail to understand the difference here.
So it's acceptable for Qt to have a CLA because it used to be proprietary, but
it's not acceptable for other software to have the same model? You do realize
that the reason why Qt is awesome is _because_ they can sell GPL exceptions, right?

Why? Do you actually think most contributors care about that? Honestly, that
sounds rather far-fetched and desperate.

Because Canonical is not the copyright holder of the majority of projects that
are included in Ubuntu.

Funny how the same people who have no problem with the Qt CLA have an issue with

You do have the same rights over your 100 lines. It's the 200k lines that you
didn't write that you don't have the same rights over.

If the belief was that the CLA would prevent people who were legally encumbered
from contributing then I completely understand the position. (That would be the
#3 I listed earlier). If it was because of #1, I do understand also, although as
an Ubuntu developer, I do think a fork would have been trivial. Debian packages
are forks from upstream, and Ubuntu packages are even more so. I have a hard
time understanding why a fork would be so difficult since maintaining forks is
basically what I do for a living.
But those are two very good reasons not to use LightDM. It's quite unfortunate,
but no different than using Qt or MySQL in your project. At some point, a
decision needs to be made as to what the best solution is long-term, and as I
explained earlier, there is absolutely nothing wrong with doing your own thing.
I think the aversion to forks and the aversion to reinventing the wheel (aka
"NIH syndrome") in the open source community is unhealthy and part of the reason
why open source licensing is not as widespread as It should be.

Not at all. The CLA is definitely a factor that enters the equation, but
pretending it's the only one is FUD.

Working together makes sense in certain situations. In other situations there
are other factors involved that make the decision difficult, such as politics,
difficulty to work with upstream, or simply a disagreement on what the project's
Without disagreements, we wouldn't have awesome projects like Apache, or
MariaDB, or LibreOffice, or NGINX in the first place. We should embrace people
thinking differently, instead of being critical of people who don't want to
collaborate on a single bloated one-size-fits-all solution.

Sorry, but I'm pretty sure some other barriers would have prevented
contributions if a simple CLA was the first thing that was blamed. Do KDE
developers not contribute to Qt? Or is Qt only used because there is no valid
