Hmmm.... delist from us stock markets headquarter abroad and base servers outside the states
Think that would pretty much nullify anything as well as stripping a lot of jobs and tax revenue from the usa
To be fair once these companies are stock market listed they have a legal obligation to protect shareholder interests ... so yeah they wont simply let it happen (or the shareholders will remove them and replace them with somebody else who wont let it happen)
Very hard for one country to try to regulate how anybody structures a global company... particularly one that is based largely online
If they are a monopoly in violation of antitrust laws, they can and should be broken up.
