I also don't like the term "free" in the context of money involved. I think it makes instant and, imo, associations in the brain that are not helpful for the project in question.
Rarely are projects of any meaningful size actually free. Someone is paying to afford the hosting/dev/etc. Sometimes that payment is in the form of donations from larger organizations. Often a mix of that and user donations. However I think it's important that we don't so easily undermine a projects funding. Especially projects as great as Blender.
I think I just long for the idea that we all recognized that many of these projects we use could do well with some basic coffee money from us all. Something somewhat like Github is setting up. $3/m to a project I make money off of means nothing to me, but from a couple thousand users it would be amazing for the sole project owner.
It's complex, I know. There's pros and cons to a lot of funding talk. Nevertheless, I just want to see great projects succeed. As Blender is.
