Copilot was made from stealing code on Github, ignoring the licenses set on repos such as e.g GPLv2, using AI as a trick to license-launder code. Copilot has announced their plans to become a paid service. So this product that would not be possible without public, open-source code will itself be non-public, closed-source, closed-data. It is extracting value from the commons and funneling it to a private company.
So what you're saying is that you have the right to host your code for free, to download it from GitHub for free (no bandwith paid) and to behave like new-age Robin Hood when it comes to being offended because the very same company use that code - not to run it, but analyze it. Stop being entitled, it's seriously hard to participate in any kind of progress with offendable cauliflowers like you.
When I uploaded my code to GitHub, it was done so with the understanding that in exchange for the hosting and bandwidth, GitHub was permitted to use the code in a set of limited ways, as spelled out in their terms of service. I understood that I was contributing to building and establishing GitHub's brand as the go-to place for open source collaboration, a brand which they have undoubtedly benefited from.
With Copilot, GitHub has extended that use in a way that was not made clear during that initial contract. Regardless of the legality of this change, it's normal and expected for some users to be "offended". This isn't "being entitled", but a legitimate response to what many perceive as a violation of the norms of this industry.
That doesn't even get to the ambiguous legal questions involved, particularly with licenses that go beyond the typical MIT/GPL licenses. Based on GitHub's statements, it sounds like any public repo was fair game. What does this mean in the context of AGPL and other more restrictive licenses?
