No, you need to demand that government organizations use Linux or other open source systems as well, there is no other way.

You can require Microsoft to comply with rules, it won’t. It doesn’t care, it wants money, and more money, and that is it. It’s been like that since it’s inception. The same goes for all other tech companies

You know what brand doesn’t careuch about money and will respect your privacy?

Open source software. Linux. Firefox (eh, mostly) with plugins, mariadb, etc…
