Upon further reflection, I have decided to delete the previous post which was critical of Matzav. I had erred in my perception of what they did. They did not necessarily deceive anyone by posting a Dvar Torah by Rabbi Wein on the Parshas HaShavua (Shelach) that was 10 years old, instead of his most recent one. Although I do wish they would have posted the new one - as one commenter pointed out Divrei Torah stand the test of time. I apologize to Matzav for misinterpreting what they did.
However, it would be prudent for them to make note of the fact that Divrei Torah that they have posted in the past be labeled as such and list the date in which it was first posted. In this way, such misunderstandings can be avoided in the future.
