I'm sure many people were pissed with Office 2010 since the 'upgrade' from Office 2003 to 2010 was a full-price affair (see http://www.computerworld.com/s/article/9143103/Microsoft_dum...). (EDIT: that was for retail, but you get the idea). So, while your 1000 machine deployment was technically straight-forward, it was probably ~ $100,000 for the software, plus your time (with patching!) financially. Lots of large companies and government find that cost not worth it given the benefit and they ultimately end up with outdated versions.
