"The reason Microsoft didn’t adopt Blink is simple: Google. Aside from the obvious issues these two companies have with each other, consider a few other relevant details. Google had split Blink from WebKit earlier because it was always fighting with Apple and wanted control. But now Google is doing what it wants with Blink—as Apple did/does with WebKit—because it’s strategically important to Google. That is, Google could only be counted on to do what was best for Google at all times, and not what was best for Blink generally, and the community of companies using it." Given how Apple and Google had the public divorce over WebKit, it makes sense that Microsoft didn't trust Google enough to base their new browser on Blink.
