Now if this is the first you're hearing of this, KOSA is a "think of the children" bill. It stands for "Kids Online Safety Act", but it's really more of a "Klansmen Online Supremacy Act". It does two terrible things.
The first is it makes platforms responsible for censoring basically anything the government orders them to. That's pretty bad. Like that's People's Republic of China bad.
The second is worse.
It requires platforms to verify the age of users. Long story short, while the proposed law doesn't specify how they are to do that, there literally is no way of doing that that does not require all internet users to show ID, and give up their legal names and residences. This is the death of anonymous and pseudonymous use of the internet.
The Nazis of course are very down with this. They are SUPER in favor of the state compiling lists of their critics' names and addresses - and even better, outsourcing the job to industry as an unfunded mandate, even.
