Of course, I don’t have any hard numbers that show that this has been what Microsoft has been doing. I just have my own impressions from their marketing pushes, product investments and anecdotes from people I know around the SharePoint world.
One anecdote came from a former colleague that works in IT on the SharePoint team for one of the major auto makers in the U.S. He told me within the last year that every time the Microsoft team shows up at the company’s headquarters, that all the MS team wants to the talk about is SharePoint Online and when the company will migrate to it.
