Just wait until Windows 10 drops support, we'll probably see a 2%-4% increase within a year. Who knows, maybe more. I was fine with Windows 10, but when I made the move to Windows 11, I said fuck no. It's what made me switch to Linux as a daily operating system. I'd say with tools like ChatGPT, it will make it much easier for your average joe to switch over. Windows has reached peak enshittification. Do more, teach people, show people how much money they can save.
I already convinced the company I started working at to replace their outdated BIOS firmware with Coreboot. And soon, we're going to start using Proxmox VE on all of our machines. We have about 40-50 computers, and we're going to install it on every single one of them (edge virtualization) and manage it them all from a server. Once that's done, we'll have even a bigger incentive to switch to Linux. I'll also soon setup Nextcloud with OnlyOffice, as a replacement for Microsoft Office. I hope to see us transition over fully.
They probably spend around $5000-$6000/more a year in licensing for software. Once we have all Free Software, I think it'll truly be better for the long run. Sure, a couple issues with people getting used to it, but these are short term issues, down the line we can save so much money and have better security/privacy.
