The article seems to make an attempt to associate him leaving with "modest" surface sales.

Maybe he was sacked. Maybe as someone suggested he finished what he was employed to do and moved on.
It is not clear from that article why he is no longer at MS.

So unless you have more info from another source both are just assumptions and not yet confirmed fact.

Surface not looking like an "ipad killer"...yet.

When asked about Surface, Steve's use of the term "modest" was in relation to the company's approach in ramping up supply and distribution of Surface with Windows RT, which has only been available via our online store and certain Microsoft retail stores in the U.S. While our approach has been modest, Steve notes the reception to the device has been "fantastic" which is why he also stated that "soon, it will be available in more countries and in more stores."
