Aniplex has never been terrible. They hire great studios to produce great dubs, and the goodies they include in their products are usually worth the purchase price (some exceptions, of course, like part 3 of SAOII which included a whopping 3 episodes because of how the story arcs are laid out, but part 4 included 9 or 10 instead.)
Yes, they are pricey, and I hate that some of their releases like Garden of Sinners and Persona are non-dubbed "imports" sold at exorbitant Japanese prices. There are also obvious problems like the fact that they generally don't re-release stuff. I want my fucking Baccano! blu-rays that I didn't know were released until it was too late, and there's no reason why the Blu-ray version of the Gurren Lagann movies shouldn't include Parallel Works... But their actual localizations are quality products at a steep, but reasonable price. They essentially succeeded where Bandai Visual failed in delivering high quality releases of their licenses.
It makes a lot of sense, honestly, and ANN's Answerman's had a couple different reponses about this recently. The only reason why anime companies like FUNi and Sentai exist today is because companies like Aniplex didn't self-publish. Now we're got them, Pony Canyon and Sunrise (in partnership with RightStuf) directly releasing stuff out here, and it doesn't make any sense why they would still have FUNi distribute their products.
Aniplex is just refusing to renew licenses with other publishers because it's their product in the first place. FUNimation owns nothing, when you dub a show, the owner of the product owns your dub, you just have a license to produce the western version of the product and sell it for mutual profit.
While I would prefer that FUNimation would keep publishing these titles as they are certainly more cost-effective, Aniplex is totally within their right to do this, please stop making this controversial.
