> 1. I think many public sector organizations in Europe lack basic knowledge of FOSS and have IT managers that don't even know what it is.

Confirmed. Source: I teach these topics in University, including in post graduate courses for public officials, and most of the students don't have a clue of what OSS means (the whole words), and don't even realize why the F matters. I usually explain what source code is, and from there all they way down to that F.

I am deeply convinced that one, if not the the most, worrying problem of our times is a general lack of proper education in all levels of societies, except for a small portion of the population.
