I think the author's characterization of "Open Source Rambos" caring more about the licensing than the software is unfair: we learned through bitter experience that if you care about the software, you need to care about the license first. Today, licensing is something that many (probably most) developers are able to ignore without repercussions. That wasn't always true, perhaps won't be true in future, and isn't true even now for those whose businesses need to sell their software or are simply a little more scrupulous about how their software is made. As someone who lived through the earlier era, it's hard not to see this as a potentially fatal weakness: an ability to bring down large chunks of the ecosystem with a single determined actor invoking legal mayhem.
