For instance, a company may not desire to hand out cash to win business; previously, when solicited they could say, "Sorry, it is illegal for me to do so." Now there is no such shield.
Second, in many cases it will be two or more US businesses trying to win business in some other country, and the change of the law only makes it more expensive for those two companies, as they now must play a game of bribery chicken to win the business.
Third, the US loves to claim it is is a democracy and is working to spread democracy. By legitimizing bribes paid to foreign officials over the interests of their voting populace, we are undermining democracy in those countries (not that anyone who pays attention believes that the US's foreign policy is anything but self interested and divorced from spreading democratic ideals).
What evidence led you to that conclusion?
Is the US not lowering it's capacity to innovate and grow it's economy by preventing the use of forced labour(even in other countries)? Why should these "guardrails" stay in place if the argument is "the reality is they are right that guardrails only serve to hurt us in the long run, at least at this pivotal point in time"?
Yes it is a fact they did build themselves up on top of mountains of copyrighted material, and that AI has a lot of potential to do harm, but if they are forced to stop or slow down foreign actors will just push forward and innovate without guardrails and we will just fall behind as the rest of the world pushes forward.
Its easy to see how foreign tech is quickly gaining ground. If they truly cared about still propping America up, they should allow some guardrails to be pushed past.
