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.
I would like to remind people of the 2016 Adups backdoor:
> According to Kryptowire, Adups engineers would have been able to collect data such as SMS messages, call logs, contact lists, geo-location data, IMSI and IMEI identifiers, and would have been able to forcibly install other apps or execute root commands on all devices.
