TLDR: "do not put work email on personal phone, as the company may ask you to install mobile device management (MDM) to manage your device, which gives them opportunity to spy / control".
This conflates two different things: work email and MDM on personal phone. While I would never install company MDM on my personal phone, many organizations allow you to access work email from personal phone, no MDM strings attached. My 2c.
