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.
China chill? The legitimate concern is that China is controlling the way certain messages are pushed (“the algorithms”) to control topics that they have an interest in. I.e. pushing misinformation to drive support for Trump or Biden, as an example. That is not free speech or privacy, that is malicious interference and the the fear of the US doing this is the sole reason China has already banned similar US apps in China. That is also the reason they would rather be banned than to “give up the algorithms” (they certainly won’t allow anyone to see how they push misinformation).
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).
