On December 7, 1995, Microsoft announced a new strategy in which it would "embrace and extend" the Internet in all of its products. Almost exactly 23 years later, on December 6, 2018, Microsoft has finally come full circle, agreeing that what really matters in that the Internet be both open and standards-based.
This is not a capitulation of any kind, though I know that many in the Microsoft user community see it that way. Instead, it is a belated realization and public admission that is previous and proprietary approach was both wrong and wrong-headed. Now, Microsoft will try a gentler and more correct approach. It will just embrace the Internet.
