So you want to limit speech in the name of protecting free speech?
Maybe I want to create a charity and am looking to raise awareness for a fundraising event I am having.
Maybe my dog ran away and I want to get the word out about a monetary reward I am offering for helping to find them.
Maybe I am a touring comedian and I want to advertise my next show.
Maybe I am an amateur photographer and want volunteer subjects to help hone my craft.
The list goes on and on for potential non-corporate uses of advertising. If we want to treat corporate speech and individual speech differently, I think there is a much more important place to start: Citizens United v. FEC.
That isn't the way it works in the US. There are some restrictions on advertising, but is fundamentally protected speech in the US and therefore can't be banned outright.
It makes it so Facebook's product becomes online photo sharing, instead of it's current product which is manipulation and addiction.
