Fuck AI

I've mentioned it in another thread about this, bug in case you really want to understand: people sign up for much more than the desktop office applications. It's a full on groupware package that comes with 1TB of cloud storage. Which automatically gives you access to your documents on any machine you use. If you get a new windows device you basically don't need to put in any effort into setting things up because it's already there. And for 80 euros you can do this for five people.

So in short: convenience for a reasonable price. To the point where it's hard to justify running it yourself. Especially because your family will start to ask you how they can get MS office again.

Office alternatives have long existed and have been good enough for a long time. I remember writing my evening class project reports in them 20 ish years ago. Funnily enough on how to integrate Linux servers into a Windows domain and authenticating with domain users on that machine. But if you want to compare M365 to something, compare it to NextCloud.
