I agree: when I signed in, I never agreed to let anybody use what I write to do anything they want ! I only agreed to let everybody read, understand, interact with what I wrote

Actually, it makes me feel as bad as knowing that CAPTCHA were used to train image recognition models...

I think it could be a good time to reconsider the question of the consent. I may agree that my words are used to train some IA... but 1) I must be asked (kindly) first and 2) it won't be free!!! (it may be paid to me or the service provider like HN... but it's NOT unpaid work ;-) )
