Is Microsoft free anymore?

Is Microsoft still the free and open-source software giant it once was, or has it transformed into a closed and proprietary entity? With its recent acquisitions and partnerships in the cryptocurrency and finance space, are we seeing a shift in Microsoft's approach to software development and distribution? Are users still able to enjoy the same level of freedom and customization they once did, or are they being increasingly locked into Microsoft's ecosystem? It's a question worth asking, as the future of software development and the role of Microsoft within it hangs in the balance.
