I think there's something to be said about how Japanese people feel about "lesbian" manga/anime/media vs. "yuri" manga/anime/media. I've noticed that distinction being made quite a bit, with the implication that yuri is preferred since it's more pleasant and accessible, and lesbian media is weird or gross, and it's easy to make a yuri manga into a lesbian manga by including too much emotional complexity or whatever. I think whether yuri manga need to address lesbian identity is a side argument; a manga could do it successfully, or it could successfully opt to not do it, but I think the real issue for yuri connoisseurs is how editors and mangaka think up these overly harsh restrictions that compromise quality.
I think the popular yuri things the article is talking about is like Senran Kagura or whatever else is in its genre. Valkyrie Drive, etc. I guess those shows are current and popular, but so are a bunch of other shows in similar numbers, just with different audiences (like how TV show is today). The author does seem pretty out of touch, and uninformed on specifics outside of the very narrow subjects she wants to talk about. The article's a bit too short and flimsy to spend much time criticizing, so whatever. It's good to talk about this stuff and increase the profile of that kind of yuri. It does grate on me though when people like this have massive blindspots for what they're trying to talk about with authority, so hopefully someone will link them Dynasty on twitter so they will correct their gaps in knowledge.
