Good guess -- Bon Jovi may be caught between the deal Spotify has with their parent label Universal, and the exclusivity deal they signed with Tidal. Universal may have either ordered Jon to pick a side, or, since he is no longer on the label's A list, picked a side for him.

Now that Bon Jovi are in the Rock Hall, maybe Spotify has determined that Richie's absence qualifies as egregious conduct.
