Quoting from the Wikipedia article on CAPTCHA:

"Breaking a CAPTCHA generally requires some effort specific to that
particular CAPTCHA implementation, and an abuser may decide that the
benefit granted by automated bypass is negated by the effort required
to engage in abuse of that system in the first place."

With that quote in mind, a hacker might be more willing to spend the time to break a CAPTCHA algorithm offered via popular web service, thinking that it would automatically compromise all the sites that relied on that particular Web service. If that matters.
