"We fixed it"

You're not wrong. It's about western influence in general. Low quality, ugly and political shows.

I guess it could affect porn (Hentai) as well...

Ok but those were like 20 years ago, that's more the "before" this meme is referring to. These days, popular anime has dubs that come out only a few days after the Japanese version is released. I haven't heard any complaints about the quality, but then again I'm not big into anime these days.
