I hear you, and fully get where you’re coming from. I work in the finance industry and we have auditors to answer to as well as a ridiculous number of compliance regulations we have to abide by. Not every business is the same. I’m personally on the no-trust policy when you have more than 50 users to manage but it also depend on company policy. No one is saying you can’t use your personal device at work. We don’t monitor the guest Wi-Fi in any way specifically because that would be an invasion of privacy. I was referring specifically to using a work device, managed by the business, for personal use. The employee is protected by being briefed during first day induction of he does and don’t with regards to the equipment that is provided to them to do their job. Their personal privacy is not infringed upon as there is a clear agreement about what is expected from them. By the way, I’m in the uk (not sure if relevant).
