I'm also baffled that Spotify does not grant verified/accomplished contributors to the platform free accounts by default. I wouldn't be surprised if a huge percentage of their premium listeners are the very same people who publish their music to the platform.
The Internet unfortunately is quickly becoming a "scam-based economy". It's flooding out all the potential it once had. I just decided to create and focus on my own personal music label web site moving forward. If I'm going to give most of my music away for pennies, I'd rather have more meaningful and useful analytics and FAR less complication in publishing my own music. :/
A lot of artists need to emulate success and fandom in order to break into paid work, and that creates a toxic situation where they need to pay up front (for various other things like SEO, interviews, artificial promotion, awards, and even for spots in gigs to get to a success point) before any real success is achieved, or they need to spend many years in unpaid (and very defeating) obscurity before finding out whether they succeed or not.
Statistics really don't apply to everyone on a consistent basis, and a lot of numbers in the mix are totally calculated in "mysterious ways" on purpose.
I focus on licensing rather than streams, that way there is more of a (tangible) contractual negotiation involved.
