Hungarians mostly don't wish to be recognized to be Hungarians, when they get the chance to be in company of admired, rich, western countries citizens. If they are not accepted by them, most turn offensive. That's a national habit accompanied by social envy and self rejection.

Most of them think of America like: "Try to be a part of it, if they reject you, offend it." (That's why Hungary joined the EU.)
This is a justified reaction, but with wrong actions taken. I think, the cake remains delicious even if one's been denied to get a slice of it.

If Ballmer would have stopped the "inquisition", then to force the guy to give statement of his opinions and a chance to dazzle the audience with his highly developed IT and business skills during their conversation, I guess, the guy would have licked up the yolk from Ballmer's head, if he would've hit.

This poor guy simply realized that nobody joined him, or at least boooh-ed with him at Ballmer after the first egg, so he went on with the second and third to save his concept, but then he got confused. (I think he was even thankful for getting stopped. He also might have seen some scenes on Youtube and tried to sample them.) However, finally his "revolution" has been set back.

Nonetheless the guy's been absolutely right with his opinion: the Hungarian state hasn't got the funds to buy the "unreliable" IT stuff from Microsoft, and the only reason they do is, that Microsoft tries to force the whole world, - using their shady business practices - to buy their products.
Some Hungarian businesses also suffered outrageous prosecutions of the local BSA. But this is a more complex situation than to discuss about here.

Besides: Hungary is one of those "new" European states, that gives the most capable IT technicians, and engineers as a result of the countries excellent higher education. LINUX developers are very talented and skilled here, and even the system itself is very popular.

This might even be the reason of Ballmer's visit (or should we rather call it "audit"?!)

I'm sure: Steve Jobs would've enjoyed a warm welcome!
