I want to say various cities/regions in Germany make statements like this every few years? And they usually end up rolling back when it becomes clear the cost to retrain both existing staff and new staff isn’t worth it.
That said: This gets the national security bump so maybe it will stick. Also nobody on the planet likes to use Teams.
And if it sticks, good. But it still has the fundamental problem of needing to re-train all your existing employees AND train new staff who haven’t been brought up in that system.
Its on a completely different scale, but plenty of tech youtubers have done the “Let’s get rid of all the Adobe in my life”. Some succeed. Most tend to come down on some variation of “I can do about 99% of what I used to do in these two or three tools. And these ten things are actually genuinely easier and more performant. But we can’t take a month off making videos to get all of our editors up to speed. And this also removes our ability to contract out an edit to someone with the industry standard workflow”. And from my professional experience in different fields, that is true. Hiring someone and then spending a week or a month so they can use YOUR tools becomes a huge burden in not too long of a time.
I really hope Germany pulls it off this time and more governments follow. But I also remember all the other times I have read this story.
