Your definition of "best" and mine are vastly different.
They exploit artists, for great profit. There's such demand that they are able to exploit many artists. The costs are so low, that they can afford to employ many more artists than will succeed. The artists love their craft so much, and are often so desperate to make it big, that they will work for ridiculously low wages AND absolutely zero job security.
We all know that distribution used to be hard, and now it is not. Distribution used to be the main reason why you needed to sign with a label, or a studio. Reaching a "good enough" level of quality used to require an enormous, up-front investment of capital. Now, it doesn't.
Kill exploiters. Reward supporters.
