I don't doubt it's a messed up industry in many ways, but even "messed up" beats "rip off 100% and give nothing back" every time.
For me as a fan of several groups, the key thing, economically speaking, is that the group is able to work on their music full time, thus maximizing their creative output and therefore, as someone who enjoys what they do, the benefits to me.
It's messed up, but the problem is Kit Dotcom steals, but at least he doesn't own any rights to music and you don't own him money once the dust settles. I could be wrong, but he is having making a Spotify clone, no?
If he is making a recording label, I'd avoid him more than the plague.
