I don't think the current world situation allow anyone to work like this without a decent support.Years 2020+ => Blender Foundation has 1.3 millions euro budget. 25% coming from Epic alone. 75% of the all budget from companies. Open source is a business.
Before talking of a software manifesto, some one should clarify me what model can sustain open source development now: I'm quite puzzled by the current situation. I'm not sure what is sustainable and what is not.
That is quite the feeling i have too about this new era. So if it become a Business it is far harder to stay alive without a clear strategy for the Futur. The current CyclesX project Will make things even harder for the Luxcore Project to grow.
We can't stay for decade as a potential super software project without getting to the level where it become healthier for Devs and Users. That new step require so move to be done.
