the argument is that unlike the West where a good drama/show can still be appreciated in Japan it needs to pander? That's insulting to the viewer but w.e. Hannibal would be a 1000 year old loli murdering dragon.
Do we not have estimates of audience #s for anime viewers by now? It has become decently popular by now I reckon.
You are confusing the late-night anime market with productions that are made differently. Shows like Log Horizon, Fullmetal Alchemist, Haikyu, and the new Gundam show are made to run in primetime timeslots via TV station input and are made to appeal to a broader audience. Those tend not to have a lot of the less desireable elements in them. Depending on how big of an influence the TV station has on the production, they may be made as an entertainment source rather than to push a product.
Shows like Space Dandy, OreImo, Fate/Stay Night, and nearly most of what gets discussed in this thread and many other forums are essentially infomercials made to push some type of product, whether that is a video game (God Eater), light novel (anything from Dengeki), video disc (Madoka), merchandise (anything waifu/husbando), manga (Kodansha/Shueisha), or anything else. They have an audience in mind that buys these items and so they have to include elements to appeal to them. This is why shows like K-On! and Euphonium had to hype the main four girls: to market to that type of audience despite the shows appealing to a broader audience.
TV stations in Japan have seen dramas obtain higher ratings than animated content, thus primetime is devoted to live-action content. Anime shows used to air around these times, but once higher ratings came about for (relatively cheaper) shows, the medium was essentially forced into this production committee/infomercial type. There are a few stations that produce anime, but they're fewer than the other type. Additionally, the TV stations are asking for more of the revenue to be a sponsor. This is why shows like Sailor Moon Crystal and Digimon Tri had to be made in alternative formats (web episodes/OVA films respectively). Toei did not want to sacrifice additional revenue for popular franchises to TV Asahi/Fuji respectively.
There are different types of anime much like there are different types of broadcasts outside Japan. Painting all of it with the "pandering" brush is inaccurate, though it applies to a subset of the medium.
