Mittlerweile haben ja schon einige große Onlinehändler einen Marktplatz in ihren Online-Shop integriert.

Auf anhieb fallen mir da z.B. ein:
Conrad.de Kaufland.de
Media Markt Otto.de
Voelkner.de
...

Für Bücher und Medien gibt es z.B. auch noch Booklooker.de

To get a better impression, all that would be needed is for a few indie artists to disclose how their payout rate is calculated down to 1000 streams per provider...

I'm still waiting for a streaming provider that pays so fairly that the subscription fees are distributed proportionally to what the user has actually heard. For example, if I pay 12 €/month and have only listened to one artist in the whole month, it should be obvious that this artist gets, for example, 70% of the 12 € and the streaming provider gets the remaining 30%. But I'll probably have to wait forever for that...

And it turns out all services are intransparent. There are no hard facts and numbers. It’s massively complicated how they calculate these payouts and seems nobody publishes the exact maths behind it.

Yes, it is indeed a problem that almost no one discloses official numbers. Qobuz at least did this once: https://community.qobuz.com/press-de/qobuz-legt-als-erster-akteur-in-der-musikindustrie-seine-durchschnittliche-vergtung-pro-stream

There are some news articles with claims and speculation, but they’re all based on the same thing and mainly copy-paste each other.

Yes, I agree with you! Of course, these articles and figures are not reliable. Here is an article with payout numbers, which also goes into more detail about how the numbers came about: https://dynamoi.com/de/learn/statistics/what-streaming-platforms-actually-pay-per-stream

Sure, they are an option, too!

Yes, but their payout is only slightly higher than Spotify...

Here's a good read about streaming payouts in 2025: https://rebelmusicdistribution.com/2025/08/22/which-streaming-service-pays-the-most-per-1000-streams-in-2025-top-5-platforms/

Qobuz (who payout the most beside Napster) is a European company.

Besides the political aspects... The main reason why Spotify should be boycotted is the fact that they exploit artists (small and large artists receive virtually nothing for their streamed music) and flood the market with AI-generated music...

Have you already had a look at https://metager.de/?

Bandwagon.fm is a great project, but unfortunately, ActivityPub/Federation is not yet reliably implemented and has too many bugs.

For example, if you follow a Pixelfed account and then unfollow, the follow remains on Pixelfed!

In my opinion, the ActivityPub part of bandwagon.fm is unfortunately not yet production-ready and should be tested and fixed more thoroughly.

Don't forget the instance operators! How can we get them more donations?

I recently found out about https://crowdbucks.fund/ (which is done for the Fediverse) and https://liberapay.com/

Maybe a first step would be to offer a native way to link to such donation platforms (link on the user profile, link on each posting, ...)

Also donations for the instance should be promoted more prominent.

Not everybody is so kind. In Germany, for example, lawyers are quite quick to issue cease-and-desist letters, which always involve costs. I've heard of Friendica instances that have already run into legal problems because, for example, copyrighted images were posted/federated. You're being a bit too naive about that.

The lack of monetization is certainly one reason. On the other hand, YouTube was already successful long before monetization existed.

Sure, discoverability is another reason why PeerTube isn't progressing. But I was more concerned with why it might not be successful even then. And the lack of content is indirectly related to my argument.
