If MS were serious about getting people to stop using IE they would have backported Edge to Windows 7 and removed IE from 10.
But it is all about money, MS will continue to support IE just like they will continue to produce stand alone versions of Office for some considerable time to come, because big businesses demand it. If a corporation with thousands of clients that currently uses IE and can't use cloudy office versions, were to suddenly find that the latest MS products don't support these legacy techs, they may think twice about upgrading or god forbid actually switch to Linux.
