I've always used MIT or Apache for my public repos, but I don't feel comfortable if they build a product based on subscriptions using my code. What license should I use, to avoid copilot being trained on my code? Ignoring the fact they are not currently respecting the licenses...
Isn’t the point of MIT that the code can be reused in whatever way and for whatever purpose they please?
(As long as the copyright notice is retained of course, which in this case isn’t.)
I’ve begun leaning heavily toward GPL for this reason.
There is no copyright license that allows the public to read code but not learn from it.
AGPL is the most aggressive copyleft license available, but even that can't stop a well funded tech giant from taking whatever they want. You need to use AGPL, and retain a well-researched legal team.
