It wasn't their president, it was their congress and senate (republicans)... But Trump wants his stuff done, he will do favours for the republicans.
I remember reading about George Washington, as president he spent years rapping people on the knuckles in congress and the senate, that were trying to make him a King, change the constitution to their benifit,or other stupid stuff that didn't benefit all Americans.
The internet is the new big business thing with advertisers going there, because that's where the people are going. Look at Facebook, Amazon, Google, their founders and companies together are worth hundreds of billions of dollars. And yes the old guard are striking back at their revenue sources... (more advertise on those companies then they do in newspapers now ; that's why newspapers are failing across Canada and US).
As I understand the US bill is supposed to target slave trafficking and people that exploit minors. The latest bill is targeting the owners of the companies like backpage, and holding them accountable because its where escorts/SW advertise their services. The thought process is that the escorts are being manipulated... But how much were criminals, trafficking women or minors advertising on backpage? For the few that are criminals I hope they get caught, its just sad for the majority that aren't.
Everyone knows that congressmen and senators are corrupt, so maybe the people that support them (with donations) might be the ones behind the majority of trafficking and they needed to shut down their competition on the internet in the name of justice. Trafficking will continue and so will the exploiting of minors, it just will be taken underground where law enforcement can't see it.
Think about the history of where escorts advertised. Yellow pages, Craigslist, Backpage, Newspapers, - slowly its all being shut down, the new law in the states prevents anyone from opening up the same type of advertising in the states, VPN to hide your online activities, eventually there will be laws against having A VPN outside your country! All under terrorism, fighting organized crime etc...
The freedom of information is being suppressed. Look at how one sided news shows are now. Very few present both sides of an issue. Newspaper and TV news shows have been slowly downsizing on reporters because they don't have the ad revenue they did 15 years ago. Good Reporting is slowly drying up and being replaced with one sided political views.
