I am far from a Mishpacha fan. I think even less of Ami. However, I think that some people are getting confused here. Neither of these mags/rags claim to be the mouthpiece of any form of Da'as Torah. They are merely Kosher entertainment. Just like there are some Hechsherim that have standards lower than yours, there is kosher reading material whose standards don't match yours. If you don't approve, fine, don't buy it. But if someone else does, why does that bother you?
Unless you think that an uneducated reader may swallow their stories as the true Torah Hashkafa and you think it's necessary to alert them. But that doesn't necessarily mean to cancel a subscription, only to be aware of what the magazine does or doesn't claim to be.
