Germany and Sweden are not China. They have extremely federalized governments. They are also part of the US-based economic system with a lot of neoliberal principles. Their voters pay a lot of tax and they do not really want to pay the price of going fully independent. Microsoft as many US companies got an edge in the 90s due to DoD contracts and corporate contracts. There are many European companies whose systems are deeply tied into Microsoft (one example, the whole restricted info labeling system of Siemens was deeply integrated with Office 365, SharePoint and Exchange when I worked there)

Basically migrating away from Microsoft has always a significant cost even for partial replacements. The democratic systems and shareholder pressure makes it hard to keep long-term projects going in the Western countries and companies. Choosing Microsoft has never costed an election nor caused significant share price but going against it has economic and legal risks.

So without a dictating government with nuclear reasons, you will not get enough pressure to move away.
