Reality being that which doesn't go away if you dislike it, I recommend you look
carefully at those supposed tech magazines with “less” of the young male focus that you claim exist. You'll find that they don't, really, outside of quasi-academic magazines like CACM. Even there, it's hard. How many women are on staff? How many of the articles are written by women? How much do the articles focus on metrics, measurements, and numbers as opposed to usability? I really like reading AnandTech, but as a tech magazine that isn't interested in booth babes, it is
still deeply focussed on the male interest and experience with tech, as the masthead (
http://www.anandtech.com/home/about) with it's conspicuous lack of women on staff indicates.
Reality being that which doesn't go away if you dislike it, the reality is that there are no mainstream tech/gear magazines—online or print—that don't use a hypothetical young male as the primary audience for that magazine, doing a disservice to both those young men and the young women who might be interested but aren't interested in the editorial slant involved.
Reality being that which doesn't go away if you dislike it, you're a guy—as am I—and we don't actually get to say that something we like is not sexist in its nature. There are things that I will read that I know are sexist (and not care that they are because I want to read them anyway), but I don't get to pretend that they aren't sexist just because I like them.
Reality, indeed.
