"[…] in reality, bigger companies move slower. I don't really think this is a good excuse - if policies and processes mean it takes 5 months to release an update, then the policies and processes need improving. If a big company can't work as efficiently as a small company, then the big company should act as smaller companies."

This seems really naive to me. If Microsoft could just "act as smaller companies" on directive, they wouldn't be in the mess they're in.

Of course, on the other side, a MS employee simply stating that big companies move slower like it's an unchangeable law of nature gives a little insight into the problem as well.
