As more and more of our civic discourse moves online, there are no "public spaces" online where the rule of law and public interest comes first.
There is no town square, no soapbox in the park, no public access TV, or the ability for masses to organize and march or protest (or whatever the online equivalent is), with only the government's laws as written to contend with.
Everything (that has meaningful reach and impact) is private, and all these meeting and communication spaces have a company with shareholders and therefore goals and motivations that override public interest.
I certainly don't have the answer to this problem but this erosion is a problem that will need to be reckoned with at some point.
