Actually, almost everything you wrote is untrue. If you actually read the text of the Federal Act on the Surveillance of Post and Telecommunications (which is publicly available in French and German), you will see that instead of targeting ProtonMail and ProtonVPN, the legislation actually does the opposite, and explicitly exempts all but the largest telcos.
You don't have to take our word for this, it's actually in the text of the law.
Also, if you read the actual text of the US/Switzerland MLAT (mutual lateral assistance treaty), or the text of the Swiss Data Protection Act, you will see that "unlimited power without any meaningful control" is also patently untrue, and there are many layers of control and an explicit need to satisfy the requirements of Swiss privacy laws, even on cases originating from the US.
