I have switched my small swiss business (10 people) to linux (servers and desktops) and away from microsoft around 2020. I am extemely happy about the choice. Theres small friction here and there with clients that rely on certain software, but its usually minimal and can be fixed. Some people here talk about how people need excel and how important it was, I have personally never seen that in practice here with any client or company I worked for in the past, but maybe it just went past me. It has not been an issue for me in the past 6 years.
