The Spotify Car Thing cost $100, but I can't use it anymore.
EDIT: The only reason why I still had it at this point was because I could use it with other apps. However, now that my Spotify Subscription is cancelled, it doesn't work with anything. It's mildly infuriating because today, I can't still use it with other apps like I was able to yesterday.
Please don't make the same mistake I made. No one should buy this.
I have a car thing, I use it at my desk for media controls. It is pretty great.
But the product description was pretty clear that you needed premium to use it. The same goes for using any third party Spotify client. Shouldn't have expected otherwise.
But the point is that the description of the product clearly stated it needs a subscription to function. You literally buy it with that understanding. If you didn't read the description then it's 100% on you.
Whether it should be legal or not, or whether it's ethical or not, is a different discussion. But the product wasn't disingenuous about how it works, so complaining about how it works exactly as advertised is a bit silly.
Look out! Communists are coming for your toothbrush. Better vote for harsher penalties for modifying stuff you bought. The DMCA still allows throwing away or disconnecting the computer locking you out of your heated seats.
