For most people, if they want any kind of home automation then they’d have to trust someone, as most people won’t be able to deploy and maintain their own system. So now you have 2 options (other than just not automating your home)

• Trust a company you already have to trust (since they provide the OS and hardware for your computer, phone, tablet, watch, etc.)
• Trust an additional company

So would you rather bet on 1 company not being evil, or 2 companies not being evil?
