Everyone should immediately stop contributing to the stack overflow and its network. The human touch is what made it unique. Delete your profile from SO AND all your answers. Freeloaders are making money out of human contributions.
@nixCraft Stack Overflow uses a copyleft license for its answers. Under that same logic, Wikipedians should start deleting the pages they contributed on so that AI can't use them as training data... but then again, that's in the scope of what copyleft is supposed to allow in the first place
