I think that the first had some free stuff, at least after enough money was
raised:

But this doesn't seem normal anymore though. You're totally right - They
should be selling only free software. I don't give them any money for that
reason.
One challenge I see with setting a particular funding level in order to make
a program free (like that link... raise one million dollars and it becomes
free) is that is seems kinda like a chicken and egg problem to get started. I
might be interested in supporting a free game, but I wouldn't until the
goal's been achieved. If they were to offer full refunds if they don't
achieve their goal that might sway my decision in the direction to support it
but if they don't achieve it (like maybe they "only" get $800,000) and don't
have such a policy then all I really would have done in the end is supported
a proprietary game.
I'd like to see more people doing what onpon4 is doing and developing free
games commercially. Free from the start. Not free code with non-free
graphics/sounds. Or that start proprietary and are made free later on when
the code is thrown over the wall (and no longer compiles or runs on modern
systems), etc.
