Is it also a fully-remote company or do they have offices? My experience with Canonical has been pretty good from a customer perspective but I did have one sales guy call me with the most ridiculous levels of background noise.
I can only imagine that the amount of money you have to spend on IT for a myriad of different devices + the security implications + the hurdle to get non-technical people to manage their own devices is just not worth it. Let's say amazon has 100k white-collar workers. If they all the 1k USD devices on avg that's 100mio dollars. That's < 0.1% of their !quarterly! revenue.
