The next step would be for the government to demand direct access to these tools. Then the government would be able to carry out holocausts against any ethnic group, only 10 times more effectively and inevitably than Hitler did.
You've got this the wrong way around. These are social media sites.
People are publicly publishing revenge porn, and the government has told sites that if they are requested to take down revenge porn then they have to.
They don't have to monitor, because they are being told of it's existence.
As far as I understand, it precisely mandating to monitor EVERYONE.
They are not talking about removing a specific image from the platform based on its hash or something. They are talking about actions that involve automated analysis of all content on the platform for patterns arbitrarily specified by the government.
The technologies discussed differ from totalitarian surveillance by simply toggling a single flag on the platform, and are indistinguishable from such surveillance for the user.
But most people understand the word "surveillance" to mean more involved information collection than just deleting content that matches certain criteria.
In contrast to the proposed one, which should be able to classify all content on the platform at any arbitrary moment in time according to a post-factum specified arbitrary filter. Literally a mechanism of totalitarian surveillance.
