I'm very frustrated by some of the answers here and on Twitter. Carmack says: > The GPL virality wound up being a net negative, and more value would have come from BSD. [...] The best aspects of GPL work didn't manifest, but tons of opportunities to just copy-paste-modify were lost due to license concerns. One of the answers on Twitter: > Then what if it's being exploited by big techs and make your work proprietary?…
Did someone get sued for downloading a copy of a game with the quake source code in it?
Did someone release a game with quake code in it, only to go after users for patent infringement?
DRM locked devices built on the quake code?
A license is simply the condition for which an author allows others to do things for which copyright law make illegal. There is also a culture and a movement that has been built around common rules for software development.
Carmack does not explain what he wanted out of the license, and so people attempt to fill in the gaps. That people interpret that as "Dismissing empirical evidence" is on those making that interpretation. I do have a word for that, but we should strive to improve the tone on HN and so its better to just explain the purpose of those who replied to Carmack.
(I don't flag comments often but this is a prime example. Hugely frustrated, dismissive, with a bit snarky tone. The comment would be hugely improved by simply skipping the last paragraph. The outcome? A bunch of up and down votes in all the comments below in typical flame war fashion)
