The case involved someone on his state's sex offender registry. He was also prohibited from accessing social media sites, and got in trouble for posting a complaint about a traffic ticket on Facebook.
The actual ruling is that not allowing him on any social media site for any reason was too broad. Apparently the opinion makes comments about how important internet access is to modern society, which does give a hint about how the court might rule in the future, but a concurring opinion says there's no need to go off into the weeds for that discussion.
Perhaps we're reading it differently, but to me, the headline says "you can't be banned from the internet as a whole", not "you can't be banned from a narrowly-tailored subset of the internet".
I was responding to the questions "With this supreme court ruling, how prisons in the US are going to allow inmates to have access to the real Internet? I mean you can not ban those inmates from accessing the Internet, right?"
Does anyone? NSA and all ...
That's for the best. Reform and all that.
You can NOT ban someone from the Internet but you may deny access to Internet in prisons.
I think this would be relevant to someone who has committed a crime using a computer and remains banned from using the internet even after finishing a prison sentence (like the kid in the movie Hackers). It doesn't sound like that can happen now.
Suppose someone is caught with an internet phone in jail and is hauled in front of a judge. If it's banned, then they can have their jail term increased.
"Access to the Internet" is the right. Not the tools to access the internet.
With this supreme court ruling, how prisons in the US are going to allow inmates to have access to the real Internet? I mean you can not ban those inmates from accessing the Internet, right?
