I also use a VPN at all times. I expect VPN's to be banned. I expect HATO to get dragged into direct combat with Russia by Macron putting officially French army boots on the ground and quickly to require HATO to rescue them. The result of that will be wartime powers treating encrypted and anonymous communications as espionage and acts of war. I doubt any VPN provider will put up much of a fight against military occupation and seizure of their offices and hardware.

These things concatenate. Without actual infrastructure we own, ISP's can decline to transmit anything encrypted through their pipes. During war, even if a crypto network did exist, they could just seize it.
