As a reminder, Switzerland has its own surveillance scandal in its past, the so-called "Fichenskandal" [0] during which almost 1 million people were under surveillance (out of approximately 7 million), between 1900 and 1990. [0] https://de.wikipedia.org/wiki/Fichenskandal (german language)
In 1994, a digital equivalent was born: A database called "ISIS". In 2010, a review showed that more than 230 000 people and organizations were registered once again. NDB, the federal intelligence service, collected data without checking if it is relevant. After a mandatory cleanup, this database is now said to only contain about 30 000 entities. The outcry was much smaller that time.
Now, my fellow citizens voted to be properly surveilled. And this time, we'll do it right and probably collect everything, including looking at any traffic flowing through Switzerland. That will be easy, since a recently passed law called "BÜPF" forces every swiss provider to retain metadata for six months, make realtime surveillance possible, decrypt data if they helped encrypt it and pay themselves for the necessary surveillance equipment (they will be reimbursed for every surveillance case).
I voted against it, but the writing was on the wall. Well-propagated irrational fear beats common sense. Maybe the checks and balances will be properly implemented this time, but I'm not counting on it.
