I think the courts are much better suited to resolving this kind of issue, because it's very product and advertising specific. Courts could easily rule that e.g. Spotify breached the covenant of good faith and fair dealing, or possibly civil fraud, or something else, by failing to prominently disclose the minimum number of years / bricking the devices too soon.

A judicial solution would be much more measured and flexible.

Unfortunately, lawyers and courts have a undeservedly bad reputation which is often created by poor legislation which is beset by political motives and disadvantaged by having to draft prospective rules that can apply to a broad set of differing circumstances.

Edit: Why don't court do this more? Often because of terrible, over-reaching legislation: https://en.wikipedia.org/wiki/Federal_Arbitration_Act
