Nope
I work on embedded security which is why there is no IoT shit at home.
I am forced to be tech support for my family, which is why they have iPhones and why i support locked-down hardware - less pain for me removing sideloaded shit than when they had Android devices.
I am bored of maintaining things - i just want them to work, which is why my WRT54G is gone and I use UniFi gear.
And I am tired of "slightly annoying, but i am supporting open source", i just want my laptop to wake up from sleep every time and last a while day, which is why I use a MacBook.
If it was open source IN ADDITION to doing everything else i want, sure. Being open source by itself is NOT a feature i am willing to pay for with any inconvenience. And being locked down IS a convenience when you are managing devices for people with no digital hygiene (aka: family)
If, if only, in my mouth -- mushroom grew, well then it would not be a mouth, it would be a garden. (The point is to not engage in impossible hypotheticals)
I don't see why there can't be a well-funded effort to build a powerful MDM for Linux, but to my knowledge no one comes close. I'd think it would be very profitable.
