So if a magazine wants to sell the maximum amount of copies, it goes to the "highest common denominator".
What % of chassidishe ppl have smartphones? ( Of course there are but the number is under 50% IMHO )
And those that have how many are on DDF? And many of them aren't the Frum ones.
Regarding chassidish people here on DDF: Actually, yes, most chassidish people in my circles do not have smartphones, or computers with Internet access, and are not posting on JS for the simple reason that they spend little time on the Internet, and when they do, it's for online banking, travel arranging etc. and not for "shmoozing".
So they are definitely heavily underrepresented here. And many of these are the ones buying the Mishpacha etc., since they don't buy magazines like National Geographic, Time, or Popular Science, nor do they have access to online articles.
And for them, sending a letter to the editor is more of a hassle than those hundreds of people shooting off emails to the editor as part of a mass protest, so Mishpacha won't necessarily even hear their voices.
Also, it's not something they are going to fight over. If Mishpacha is going to go against their principles, they simply will stop buying.
