Basically all service providers in the EU will be forced to change their terms of service that all users will have to agree to in order to continue using the service. You will simply get an “updated terms service” notification with a link and one big “OK” button and nothing else. If you follow the link to the terms of service, somewhere deep down (like page 276 of 389) it will says “I agree to be monitored”. You now have the choice to uninstall the app or to click “OK”. It’s basically everything. Obviously Google, Outlook, Yahoo etc and all the Chat apps (Signal, Telegram, Whatsapp) etc. So “Consent” is not really optional if you want to use any internet service, they can just pretend that it is so that can go on an uncontrolled unwarranted spying rampage against everyone and of course for everything.
Just restrict network access (both in and out) with proper (trusted) hardware firewall. It’s much safer that relying on disabling / configuring etc. You can’t attack what you can’t reach (directly or in reverse).
