If I tie my skills, products, and services to Microsoft, and they discontinue whatever I relied on, then my investment stops being valuable; worse, the skills I built are no longer useful, and my human capital diminishes. If I build skills and products that aren't tightly tied to some other company, then my future is more certain.
If I don't invest in Microsoft, they can't pull the rug out from under me, and they can't change the terms on me. They might not be as unreliable as Google, but they're not exactly a charity.
I can and should insulate myself and my business against corporate bullying.
And nothing of value was lost
