This was because of Allan Klein who basically shafted the Stones and got the rights to most of their 60s output until his death https://en.wikipedia.org/wiki/Bitter_Sweet_Symphony https://andrewgoutman.com/rolling-stones-allen-klein-battle/

so when he died Jagger and Richards gave the publishing rights back.

Every few years this thing comes up and people make it sound like The Stones screwed over the Verve and then someone comes along and clarifies the issue but for some reason the next time it comes back up it is still the same confusion.
