A lot I expect. There were stories about VPNs being top of the App Store, etc. when the law kicked in.
Lots of people using Brave's Tor or Opera's VPN in their browsers, and free VPNs like Proton (which seems like a negative security outcome for the country to me).
I'd have thought the intel agencies would be pissed at all that data going dark, but haven't heard a peep in the media.
