I agree on the need for discernment, just as long as we don't jump to conclusions or make unwarranted implications about a person, that's all.
And again, it is indeed true that many who hold to sound Reformed Christianity do freely offer their books and recordings for free, such as those on sermonaudio.com, so we should be careful about saying too much about a person (good or bad) just because he is willing to offer his books for free.
