I agree with the activist spirit! But you have to realize that the incentives of legislators are to first create a strong economy and to maintain the dominance of the US tech sector. If you come to them with a plan that will seriously harm their operations then you won’t even get a meeting.

It wouldn't be the worst thing if tommorow Social Media was effectively banned. It's done enough wrong in the world
If you start making everyone suspicious of doing business with US, that dominance will slow fade away as each market tries their home grown alternatives.
Yes they will suck during the first years, get barely enough customers to survive, but eventually they will get there with enough perseverance.
The current administration is only making everyone aware that the globalisation days are over.
