Everyone who's said that to me, or something similar, has usually always followed it up with something like "I know they won't bang my cc, or install spyware, etc etc". They'll mention a couple of tubes where they got spyware then they "found a good one".
Most of the people I know aren't really concerned either way about free vs pay. They're concerned about dropping $150 @ the local PC shop to get the virus'/spyware removed.
And that's when I tell them URL's of sites I trust. I can look in the CCBill admin right now and see about 30 names I recognize.
However, I do know a lot of free loader college kids who'll only look at youporn/pornhub, etc. I know just as many people who don't "mind" paying as long as they get their money's worth, too.
