Justice Anthony Kennedy espoused the idea that blocking sex offenders from social media was akin to blocking them from full range of free speech options available in public spaces like parks and street corners.

But, they aren't public, they are private. I am all for free speech in the public square, but social media isn't a public platform. I applaud those sites that try to be open to all speech as opposed to those that seem to censor one side verse the other, but it still is their choice. Just because it is free, doesn't mean it is public. When it is free, your information is what for sale.
