The chatcontrol law does not require scanning on the OS level.
The chatcontrol law requires scanning on the ISP level and on the internet service level.
That means:
* ISPs are required to check for connections to flagged servers. They also have to check for illegal URLs (yes, HTTPS will make that pointless)
* Services like chat/e-mail/file-sharing services need to effectively check if a user is sending illegal material (no, the law doesn't take into account the complexity of open source ecosystems and the many options you have for client software and server hosting options)
