FTA:

“built to last

Crafted with quality materials and backed by software updates for 5 years, Minimal is built to stand the test of time.”

I don’t think 5 years is a long period for “built to last”.

And that is is ignoring that I’d bet on the company existing for that long.

Ideally, a manufacturer making such a product would put the source of the OS in escrow with a guarantee to release it under an open license if the company stopped releasing security updates for x months.
