Your statement sounds very akin to "fine, kick me out of this party I was clearly enjoying, I don't want to associate with these kind of people anyway..." which feels disingenuous.
I think you really just don't care that much about using spotify, which is a perfectly cromulent opinion.
I think anybody that can say they "care a lot" about using Spotify pays for a subscription.
I don't like the increasingly intrusive behaviors from big tech companies, and this case with free Spotify is a good example. If they can't provide a free service without privacy intrusions, they shouldn't offer it. Radios and broadcast TV survive on ad-based model without privacy intrusions.
I think privacy is what the majority of people who use these blockers are trying to get. I know that is the reason I use ad blockers at least. I do have a right to privacy, and the amount of information advertisers can learn about me though meta data is a serious violation of that privacy. Unfortunately with targeted advertising, then line between ads and tracking has disappeared, they are one and the same. And yes, I am aware that a lot of advertisers allow you to disable targeted ads- however they still collect the same amount of information, they just claim not to use it for their ad choices.
