Then why don't you just do that? Listen (read carefully)!

I never claimed, that those (theoretical) benefits are always, without fail, realized in practice.

You actually have to turn the theory into practice to benefit from the advantages of open source. It is neither my fault nor the fault of FLOSS, if you lack the skills to do that yourself. At least I showed you a way out of that dilemma.
You would have recognized that, had you listened.

Sure there are some FLOSS zealots out there who won't see that there is a gap between therory and practice that has to be bridged to make the idea work.
But lumping me in with those people using statements that actually contradict my chain of arguments just show that it's you who isn't listening.
