One point that stuck with me was talking about the trade effects on the pacific island nations. Nations without proper access to anything thanks to isolation. I remember listening to FOSS make the case the case that those islands should be using Linux and not windows.
I remember making the conjecture these people where basic users, without access to proper education, and needed a monolithic MS style set up to keep them afloat, also people often without internet access, or reliable power (or even drinking water ATM). The response back was a blunt "oh well bad luck for them, thats not our problem".
That was the first time I became aware FOSS being used as an economic weapon, and in such a way that could cause entire populations of people to suffer.
And why? it sure as hell wasn't about making the world a better place, they made that perfectly clear. No it was about making money for themselves by hurting other people.
