While I'm not going to be terribly upset over the loss of IE11, I am very disappointed to see that Microsoft has retroactively changed the support lifecycle of Internet Explorer.
As a component of the OS, it should have been supported for as long as the OS is supported (as shown on the Microsoft website previously):

I'm sure many will be happy to see IE11 go, but if Microsoft is now making a habit of ignoring its own lifecycle policies (see .NET Framework < 4.6.1 for another example), what's the point in having them?
How can customers ever be confident that the Microsoft products they buy will be supported for the advertised period?
