Even if this weren't an egregious disregard for Jesus casting out the temple charlatans, why are these guys advertising?
A) You gotta pay to run ads. They're making money.
B) Who are they advertising to? Obviously they're looking for terms like "jehovahs witness" and "JW". Which leads to...
C) They screwed up by advertising on a predominantly ex-JW site. Well done.
I have to admit, it is pretty odd and rather silly to advertise products to such narrow and unique niche. I cannot imagine another company wanting to come up with products only for JWs to compete with that one.
And as I type, well, I'm thinking maybe not so fast. Maybe that company may want to expand their markets, maybe starting to sell and distribute other products, maybe aiming at enslaving JWs into buying pretty much everything else they sell. In that regard, if that's their vision, then the advertising works well to make JWs believe that they are a legitimate entity. Hmm, I wonder. I guess time will tell.
