Important point missed by this article is that if Netflix really wants to compete with anime they need to massively improve their subtitles. Every subtitled show I've seen on Netflix has been awful to watch because of basic errors. I feel like fans will really be put off by this unless they up their game considerably.
Another problem they will have is that they’re going to have to work really hard to pull in enough content to fill their buffers, but as you go farther afield with Animè, you will find more and more cultural ... oddities ... that are baked into the premises which simply won’t work at all with most western audiences.
And a lot of that will be made according to different cultural norms regarding the depiction of sexual activity or sexual themes.
Crunchyroll only starts to scratch the surface there, but probably > 75% of that would never be seen as acceptable on Netflix.
