The new base map imagery was preceded by the Timelapse release last month, which used basically the same techniques on historical data. See: <http://world.time.com/timelapse/> and <http://earthengine.google.org/>. It ought to be pretty clear that both of these have been in the works for a long time.
If you seriously believe that _any_ mapping provider (including Microsoft, Nokia, or Google) hasn't been actively removing clouds from their imagery for a very, very long time, then you haven't been paying attention. No one needed MapBox to give them the idea of removing the giant patches of white obscuring everything in view.
In any case, your willingness to comment on a subject that you obviously know little about -- and then extrapolate your wrongness into a statement about the industry -- is impressive. Every sentence of your original post is wrong.
