Even if you run Windows rather than Linux, you can run Linux inside Windows through WSL. Microsoft doesn't have to pay Linux, or the country of Finland, for that. It's a common good that everyone, including Microsoft, can use. It took Microsoft a while to adjust. Some of its leaders initially called Linux something like a cancer, but later they changed course and joined forces with GitHub. More recently, Microsoft signed a statement with Nvidia and others saying that openness is good for security. It took time to come around. But for this generation, open source, such as Linux, Android, Signal and Wikipedia, is part of everyday life. It is now entirely normal to see open source as a counterweight to excessive concentration.
