As far as I'm concerned, they (the EU) can ban every VPN that exists for any crazy reason they can think of, but if they think that's going to achieve anything, they're sorely mistaken. Real criminals use Tor and various other much more sophisticated methods to conceal their identity, not VPNs, whose security is actually at a very low level.
It will achieve some thing in my opinion. Privacy has to be gone and out lawed. This is not even my thoughts any more, do not forget the Welcome to 2030 essay! The age verification. The European Digital Identity. Every thing is scheduled to only make Privacy tougher to achieve or even out lawed!
Tor is already known as the 'dark side' of the Internet where all crime happens. If Tor becomes illegal tomorrow, I can assure you over 90 percent of people would think this is a good thing because it was powering all the crime. I actually believe CreepyUncleJoe is closer to the truth. Because when you think about it. They would be stupid to seize the lower security options such as VPNs while leaving Tor out in the wild when if they did the other way around and cracked down on Tor first, they would leave us with only surface level Privacy which is easy for them to get under.
On the other hand. Tor Project was partially funded by United States federal agencies so it looks like they would shoot them selves in the foot if they banned what they funded them selves.
When I just remember that years ago they started withdrawing EUR 500 banknotes because they were allegedly used by criminals, I wonder what is in the minds of these people - Switzerland has banknotes of 1000 francs, which is worth approximately the same as the euro, and they have no problems with criminals and terrorists.
I am going to put my usual double layered tin foil hat on now and say that this was only one of the small but important steps in making people more used to less Cash and more Cards around. Withdrawing a 500 Euro bank note here, adding taxes to Cash on Delivery orders and almost forcing people to pay by Card by making it way more possible for Cash terminals to have a longer queue there, they are all restricting so much on Cash payments that it makes you look at the people who pay by Card and say, 'why am I the stupid one sitting in a queue?'.
