It seems to me that the only thing more devastating for a lot of developers would be npmjs.com blowing up like this because they desperately needed funding. But they got acquired by parties in no rush to profit off them Why didn't any of the big tech acquire Docker and their registry? They don't appear to be less interesting than npmjs considering technology or ecosystem. Did they resist being acquired and has the opportunity passed ?
