I've been involved in the open-source movement in some capacity for almost a quarter century now. In all that time, I've seen a steady stream of assertions about how "open source has failed". We ignored them and we kept building.
Here's the thing: in 2003 it was from large, powerful, mainstream sources: MSNBC, NYT, etc.
Now I only see it from luddites, puritopians, and other do-nothings. Almost everyone else has to take us seriously.
Keep doing the work, my friends.
