As is typical, Watchtower condemns itself by its own words (again):
WT 2002 5/1 page 16 "Jehovah Hates the Course Of Treachery"
" However, we have reason for caution. We could miss the lessons that are implicit in Malachi 2:1-9. Are we personally alert, so that no unrighteousness is found on our lips? For example, can our family members really trust what we say? Can our spiritual brothers and sisters in the congregation do the same? It would be easy to develop the habit of couching one’s words in terms that are technically accurate but misleading. Or one might exaggerate or hide details in a business matter. Would Jehovah not see that? And if we followed such practices, would he accept sacrifices of praise from our lips?"
