This is something that I never understood with their "oh you are safe in Switzerland" bs. If the court presents them w/ a warrant they have to comply. There is no magically safe data haven and it isn't honest to pretend that they are one.
If you live in a country where homosexuality is illegal, and your local government is chasing you because of this, a Swiss company won't comply with data requests, and a Swiss judge has no reason to honour any data request.
If your local government is chasing you because of something that is recognised as a crime in Switzerland, then they will disclose data to foreign authorities.
