I would guess that they, as everyone else, have worked with MS Office all their lives and can do whatever they need without thinking much in there. But libreoffice has some small differences that will break their workflow and will spend time learning how to workaround those instead of doing what they need. For example, my grip is that in MS I can redo the last operation with ctrl+y, where in libre it's ctrl+shift+y. They could very likely allow the former to behave like the latter when redo buffet is empty, but they don't.
The problem is that doing that will begin the 3rd world war, where Israel and USA will for sure be on one side, Russia and China maybe in another. Europe, one of the last organizations that has a small glimpse of caring for their people, has been relying too much on USA armament manufacturing and is very likely screwed, but maybe (I hope) someone will tell me otherwise.
We only need that independence because we can't trust each other. There's no problem in some countries being more focused on one thing or another, as long as we are collaborating with each other without taking advantage of anyone. Unfortunately, there are still dangerous players in the world and we have to be prepared to defend against them and this capitalistic view we currently have guarantees that there's always someone taking advantage of someone else.
If you only need to worry about the IP changing, then your ISP is not using NAT, or CGNAT as it is better known. I'm pretty sure that you can also use port forwarding, which is not commonly available under CGNAT.
That's going to be a very expensive video, Linus!!
