I disagree with you and reality tends to confirm that having open tools available does not prevent closed tools usage. And there are a few reasons: as you mentioned non technical people may not care about open/closed or at least do not have this high on their priorities, then open tools often are worse than closed equivalent.

I don't mind companies being in it for making a profit, what I mind is the building of a closed web vs an open web. The closed version is doomed to fail and takes away power from the people while the open one is empowering people and gives us a chance at democracy and freedom.

Sadly this is a fight that we lost and I tend to agree with Peter Sunde, now it is a matter of damage control.
