An interesting read! Although I got a little confused at the part when the editor said that the mc for Musume no Iede was a lesbian? Pretty sure she was dating her male co-worker.
Now straight(hehe) to the point! I think Western and Japanese have different opinions regarding "yuri" content in anime and manga. While western or non-japanese yuri fans in general do not welcome yuri-bait with open arms,Japanese seem to view it as a way for revolutionising anime fans to be more comfortable for two girls to be together sexually or not? This could be arguable with an example with Hibike where the buildup between Reina and Kumiko ended quite abruptly. Then there was Shuumatsu no Izetta which subtly presented its yuri without typically fetishizing it or being made light of. It seems both potrayals brought its own fair share of dissatisfaction by noth parties.
Even so, after hearing that even japanese high school girls buy yuri magazines too, I feel that yuri subtext (not the lewd and pointless ones) is not all a bad way to slowly ease up a "traditional" country like japan to start accepting flaunted lgbt media albeit in quite a slow and frustrating manner.
Honestly I don't see much difference in the amount of yuri in shows back in the days like sailor moon and shows now. Maybe it's just the general perception of the audience. But if a day where "serious" yuri ( and lgbt related) romance anime are being regualrly aired, I'd be elated.
