I wonder if it's less about the source code here but about the people involved, and how to prevent a consolidation of capital and power in the hands of greedy financiers. Maybe developing the projects as nonprofits (like Blender or Mozilla), or at least employee co-ownership rather than VC money or institutional funders?
If only the laid off FAANGers could pool their fat checks and start up something employee-driven and not subject to outside influences, in the style of Valve or similar. And preferably with legal protections against "selling out".
