It's a statement. It's a statement by a dogmatist on one side, and there will be statements by dogmatists on the other side. Two dogmatists don't have discussions--they just try to shout one another down.
Yeah, if you get enough eyeballs on a problem, sure it might be easier to solve. But users != eyeballs. I suppose being open source, it is easier to get eyeballs on something, but it is also easier for the black hats to get eyeballs on something as well and exploit it.
In the end, neither side in the dogmatic divide is likely to listen let alone switch sides.
