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.
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.
