> Every time someone imagines a country going after Microsoft

You don't need to imagine it: the comment you are replying to links to a press release from a Government agency "going after Microsoft". And yet somehow we haven't seen Microsoft stop doing business with the Australian government.

Microsoft's key customers aren't consumers, its business and government: specifically enterprise licensing agreements. If Microsoft seriously upset business and governments, they wouldn't be profitable, if in business at all, not long after that.

Because of Microsoft's dominant position considering near ubiquitous penetration of Microsoft Office in government, one part of government will slap Microsoft on the wrist for anti-consumer practices, whilst other parts will still continue to purchase Office (and other products) because there simply isn't another product that competes directly feature-by-feature and compatibility (and usability in part), which matters in (often archaic) government processes.

It would cost far too much money to try to migrate away, at least at this point. Euro-Office[1] seems poised, if not likely, to dramatically shift that balance once it becomes a key part of EU government machinery.

It will be interesting to see how Microsoft responds to Euro-Office. If it takes off, it could invigorate other government efforts to fork Euro-Office and replace Microsoft's suite of tools. Someone just needs to put the business case to the relevant federal government stakeholders comparing the cost of (on-going) licensing vs. the cost of building an internal development team to maintain a fork for their whole-of-government machinery.

Given that there is a fair bit of EU and NATO overlap population-wise, if a significant portion of EU-based NATO countries adopt Euro-Office exclusively, I would suggest Euro-Office then poses an existential threat to Microsoft Office, and perhaps Microsoft's business productivity pursuits.

The moat that software companies had back in the 90s and 2000s before the Internet really took off, was distributing software by physical media. The Internet (as much as I have nostalgia for physical media) completely obliterated that model for mass-distribution productivity software, and indeed many others.

I'm certainly keen to give Euro-Office a test run, since the code is freely available (on GitHub too, ironically[2]).

Microsoft wouldn't do that, because it would drive away other customers too. Maybe Australia would fold or maybe they would tough it out, but most other nations (and companies!) would start thinking about how quickly they could transition away from Microsoft.

Microsoft won't get very far as a business if it starts thinking it's above the law and cuts off half the rich world as customers. Their goal, at the end of the day, is to make money. I don't know what kind of weird projection power fantasy roleplaying is going on in your head, but Microsoft is not going to cut off Australia even if they are made to honour this petty little clause that will not actually cost them anything. And even if it did, it wouldn't really matter. It's a relationship of convenience. A country can figure out an alternative if it really mattered, MS is not integral in any way, using it is just the path of least resistance. Something like ASML embargoing a country would actually be a threat, but Microsoft is very replaceable.
