When I hear karaoke I think 90s looking machine with a tethered microphone, or equally old music videos with ugly subtitles. True or not, it is possible they just want to have full control of the image of their service. Another thing is that when you sing a foreign song, the karaoke also means to read the foreign subtitles in your own language. It's an extra meaning they might want to avoid, I assume this is not a feature they have.
