It may well be the case that the fees are not enough to cover expenses, and royalty payments are a fraction of what they use to be.  At its peak, the worldwide recorded music business made four times what it makes now.  Pirating has cut very deep into profits.  If you sell CD's or vinyl or downloads or a subscription to a streaming service, you have to price it low enough that someone will pay instead of stealing the content.  I hope Spotify can successfully alter their business and get back on track; it would be worse for buyers as well as musicians if they, and other services, fail.
It's not about making money, it's about getting subscribers.  As long as people are signing up for the service they will have investors backing them.  Not paying people who you owe money to is a time-honored way of doing business with no associated long-term effects.  Just ask our President.  The title of this thread is fake news!
there's been a series of credible stories about tidal fudging its subscriber numbers and skewing royalty payments towards its artist/owners, none of which bode well. i can see tidal getting acquired by a giant wishing to expand its streaming platform (ala apple/beats); otherwise i'd surmise that they are doomed.
