The "brief P&G tirade" you refer to concerned somebody "discovering" something that looked vaguely like "666" somewhere in P&G's moon and stars logo.
So far as could be determined, it was just another rumor started by another Amway distributor.
You are now free to buy your Crest, Charmin, Crisco, Tide, Head & Shoulders and Vicks Vapo-Rub, etc. again.
I've never heard of the 666 and would have dismissed that as a bunch of dumb arses.
