I would like to also suggest greywall[1] which i found yesterday. It sandboxes the filesystem, network, syscalls, dns. The network uses a transparent proxy to see which network requests were made. Supports linux and macos.
Organize and fight the policy. Do not take your frustration out on people and companies that just try to adjust to a law. Talk to your representatives. Create educational websites similar to fightchatcontrol.eu.
You are probably talking about chat control [1]. If it passes it will break encryption in the EU and yes... politicians, police and military are exempt. It is going to be a total disaster for everyone.
