You have to install their MDM device management software on your computer. Basically that computer is theirs now. So don't plan on just handing over your laptop temporarily unless you don't mind some company completely owning your box. Still might be a validate use for people with slightly old laptops lying around, but beware trying to share this computer with your daily activities if you e.g. use a bank on a browser on this computer regularly. MDM means they can swap out your SSL certs level of computer access, please correct me if I'm wrong.
MDM is the absolute deal breaker. No way in hell will I ever make my Macbook into an unsellable brick if they so decide to lock my computer with MDM.
Even moreso, not for pennies/month
MDMs on macOS are permissioned via AccessRights, and you can verify that their permission set is fairly minimal and does not allow what you've described here (bits 0, 4, 10).
That said, their privacy posture at the cornerstone of their claims is snake oil and has gaping holes in it, so I still wouldn't trust it, but it's worth being accurate about how exactly they're messing up.
