> near-100% cut that streaming services take

All the main music services operate on the 70/30 split in favour of the license holders.

If you pay $10 for a subscription, $7 gets put into a pool with all the subscription and ad revenue for your country, and that gets divided out proportionally based on the playback in your country. If Taylor Swift gets 10% of the plays in the US, she gets 10% of the pot.

If you're of the opinion that pirating artists' music is better for them in the long run, that's cool. But at least be informed on what the business model you're complaining about actually entails.
