A Belgian minister saw a PS4 console in a terrorist's room and concluded that the bad guys used the encrypted PS4 messaging system to communicate. The newspapers ran with it and this is the official narrative even today.
Guess who gets more funding to intercept more encrypted communication? And not just in France. Italy is joining the fun too, with the postal police getting new "terror watch" units that snoop on even more stuff to keep us safe.
