It affects them, yes, but it doesn't only affect them. It's just a poison in the well tactic that can affect them. but because it isn't specific even more companies will work to "fix it". Also while it can waste resources, it doesn't stop A.I. training in most cases or render them incompetent.
For example if I add rat poison to all the local water ways, it would get rid of the pigeon problem, so it targets pigeons?
