So, in private industry, outside the buyable CIOs, and there are not to many of those, in the first rank, wordwide the benefits and risks of FOSS are now well understood, even though Meverou Nelie Kroes will shortly retire, the Regulators, bidable though they tend to be now, at least, understand the basic point.
Put another way, the genie is out of the bottle. no one now gets fired for buying Linux, but vide LSE, they DO get fired for buying M$+Accenture, if it fails, as it always does. See the latest US-DOD advice. That is enough to STFU the PHB brigade.

Voting has to be OS
Med Records need to follow Vets System
A secure desktop saves a shitload of money
Migration to non local platforms, Browser/FireFox/Chrome Chrome OS, Android, Maemo is happening, destroying all the years of M$ adopt, embrace, extend on the desktop
Java, and C# and their libraries become margenelised by Python and the cloud
