More important is how eye-opening this should be for anyone who was hurt by this, on just how dependent they are on a single vendor. Anyone running a business needs to make sure they have their own plans in place to handle outages or disappearance of any vendor.
There seems to be a notion of "I'm not bothering with it because nobody else is." and people shy away from the effort it takes to set up a safety net of fallback vendor(s).
However, as outages become more and more common, and affect more and more pieces of the increasingly integrated global infrastructure, perhaps eventually businesses will be fed up and stand up their own fallback infrastructure.
The website is way out of date, but you get the main idea. No pity for Microsoft.
