Somehow it feels great to be paid, to pay others for the tools, like in every other profession, not so much.
I frankly find LGPL more useful in cases like that, but it apparently does not work for some parties. Open-source + commercial licensing also looks like a good balance between keeping the community-developed code accessible to everyone, while allowing the parties who don't want to share to pay for the privilege.
Nothing, then get nothing as well.
Pay the work of others, than freely charge as much as they feel like.
On my repos, the only stuff I have with ROCm licenses are forks from projects where the decision was not mine to begin with.
As time has proven, shareware and trials is a much better model if one intends to make a living from software, without having it lock behind SaaS walls, or hardware.
Even street performers got their work tools from somewhere and unless they were going around the scrap yard, it wasn't at zero cost most likely.
Do you have any proof of that? Hell, are OpenWebUI even receiving VC funding?
