Maybe this works for a small-medium business, but for large enterprises (i work for a massive tech company) it doesn’t work like that.
Corporate devices are bought through enterprise service agreements, which have to go through the lawyers as well as the procurement team. Although you could get a contract from Lenovo for the actual devices, a Linux distro would have no service agreement, so that would kill it right there (+ legal would probably flag the risk of malicious code being injected into the OS, i.e. xz). Ignoring thag, devices that are onboarded need to be able to fit into existing device management solutions (ABM/MDM, EDR, DLP, AD, etc etc).
And before any of that, there would be some survey that goes out to determine how many employees would realistically make the switch. For Linux, that number would likely be so low that the business teams would decide it isn’t worth a discussion because of low business impact & user desire (not to mention that now the IT teams also need to be skilled up to support it).
I couldn’t even get a FOSS browser extension approved to be installed on my device, much less spur a movement for adding a whole new set of devices to the corporate inventory.
(Editing to add, i did talk to the IT guy and he said he wished he could give me one because he wants one too lol)
Brutal, i worked in b4 consulting before. They had Macs but you basically had to know someone to fight for it on your behalf.
I feel your pain, i struggled with a dell craptop for years. I swear to god, those things are designed to be awful.
(Although, shortly before i left i saw the new ones they were handing out which had Ryzen CPUs and actually looked pretty decent, but idk how well they worked because i left obv)
