This is true for me. I have a personal desktop, but for mobility (laptop) my work issued MacBook M1 Pro is the only thing I have. There's no reason at all to purchase a personal laptop since my company is fully remote and they purchased the laptop from apple and had it directly sent to me, and have never required me to install any kind of monitoring software or control software on it at all.
Good luck when your laptop gets scooped up in discovery/litigation. After having been through lawsuits at work there is ZERO chance of me ever putting anything personal on work equipment.
I would qualify that "tech companies that don't know what they're doing wrt IT". Apple does have some features to allow a bit of flexibility, but unless you do all of your work via VDI or similar, I'd consider non-MDM devices to be a huge red flag,
MDM does not imply surveillance. I wouldn't use it if it did. It does mean I can enforce full disk encryption and remotely wipe a machine if it is stolen, though.
