I really wish we could come up with sustainable models for not for (much) profit tech companies that was beyond our current systems of volunteer and "strategic partnerships" (as in, it's a side effect of a larger business strategy).
Basically in this model, engineers would make maybe 80-160k. No options, no equity, no "going public". No fancy offices or amenities. Just a reasonable pay, a mission for the public good, and sincere dedicated people.
I've looked hard and searched for jobs like that. Maybe wikimedia and internet archive. But yeah, can't get my emails returned so maybe that's not who they are.
