I assume he means market volatility in the US, of course, as in the EU it's likely to increase business to EU companies. I hope it does cause market volatility and businesses in the US to go out of business as that is what they deserve, mostly through no fault of their own (mostly because some of the big tech companies actively support the legislation that led to this). Maybe at that point our government will finally start to listen to its people, or more accurately, the only thing they ever listen to: money. In fact, the more businesses that close and the more businesses that lose opportunities because of our anti-privacy, anti-security laws, the better.
What other kind of response could you possibly have towards a country that has unlimited, unfettered access to ALL its businesses' data without needing any legal resource or process to get it?
