So it was pretty interesting to then see some of the same content suddenly show up in the other mag around the same time ours hit news stands.
Coincidence that both magazines are discussing new products for the new movie coming out, and reflecting the state of ST as it stands today? Yeah...

I'd quit the suggestions of possible espionage and just let the fans buy one, both or neither of the magazine lines and see what happens. I'm yet to see your magazine yet, but every time you leap to defend it (and your collectibles book), I feel uneasy. Fans are discerning people and they'll either like your work, or they won't. Either they feel there's a need for your magazine, or they won't.
Defending your decisions here isn't going to make people who don't like it, to suddenly change their mind and buy it anyway. And regular STM readers aren't going to stop buying that magazine just because both magazines might sometimes discuss similar material.
