There are forces pushing for chat control again and again and again, until one day people are not vigilant enough to prevent this BS from happening. Then it will take ages to repeal and repair the damage done. Once there is some chance to vacuum up some personal data, businesses, government, and security forces will be very quick to grab that chance, and very slow to give that data up again, should it turn out, that the whole damn thing was illegal all along, due to some constitution. The malpractices might continue for years even after things have been declared illegal.
