> Free software is software that gives you the user the freedom to share, study and modify it. We call this free software because the user is free. [2]
I believe you'd agree that everything-as-a-service and tivoized products do not make users free, even if they technically don't violate the terms of FOSS-licensed code that they incorporate.
> The Business Source Licence
Yes, I've heard about that license, but I think it's mostly applicable when an already existing company decides to make its product more open, while I was thinking of the opposite — a group of independent contributors realizing "hey, we've made something big, let's protect our work (and potentially get rewarded for our efforts)" and creating a more formal entity around it.
