The business model doesn't matter.

I can write something with Microsoft tech and expect it with reasonable likelihood to work in 10 years (even their service-based stuff), but can't say the same about anything from Google.

That alone stops me/my org buying stuff from Google.

I'm not contending that Microsoft and Google are equivalent in this regard, I'm saying that Microsoft does have a history of releasing technologies and then letting them stagnate.
