Psychologists will tell you that you shouldn't put too much faith in what people tell you about their reasons. Both because people are bad at introspection and/or try to put a spin on things, and because for most things a single reason doesn't even exist. (See also "Why did you buy product X", a question subject to much study).
Well, that's a Catch-22 and a half if there ever was one. Absence of detection doesn't mean absence of malware, it just means you haven't found out how badly you've been infected. The paid-for guys are halfways in the pockets of people who've paid more and the free guys are lagging behind.
Frankly, I'm not sure how many of their clients (being one myself) care if they publicize anything, as long as they protect against it.
