What happens when one of those services (ex: Spotify) gets hacked ? First thing that happens, is that Bob's password gets leaked online publicly, his password may even end up in the popular password wordlists like in seclists . This means, that a potential hacker may gain access in not only bob's spotify account, but also in all of his other accounts , since Bob used the same password everywhere.
