My point was not whether "banning tools that were 'snuck in through the back door'" is childish or fair or unfair. That's not even relevant. The point was that they have the power to do this and they do not hesitate to use it. Occasionally they even have valid reasons related to security and business continuity. Remember how all those defense / intelligence secrets walked out of the door on a USB stick and ended up on Wikileaks?

There is no place for idealism in selling to BigCos. You have to work through the process and build your case or someone else will steal your deal, possibly with an inferior product.
