During the run-up to the Iraq war after 9/11, US ISPs with or without the blessing of the government blocked Arabic news sites, pretty sure Al-arabiya was among them at the time. That was before the Patriot Act, even. People would get on London-bound flights and be amazed at the copies of British newspapers calling out GWB for being a crusading asshole and, especially, calling out the pro-Israeli stance/people who had a lot to do with it.
So, since then, the US government has appeared to take a back seat while letting Silicon Valley drive. The government shuts down most TV towers because cable, DVD recorders no longer work but you get HD, what you really need is Alexa or really Google Home. RIAA puts up with extensions that let people download songs off YT or off the regular Internet while making sure they see lots and lots of ads. Tor, torrents /bitcoin become entrenched as something only drug dealers/CP/terrorists would use. If you got kicked off Twitter/FB/Reddit/WordPress etc., you must be one of those marginal people society should avoid. Because, let's let Silicon Valley drive, because it'll do so on behalf of the establishment, and it'll keep our "safe spaces" safe.
Now, SV is thinking that because they were too "lenient" w/social media that resulted in people electing Trump when in fact a lot of that was Americans being fed up with being told what to think. A public that is increasingly reliant on their platforms.
