Trackers are not necessarily evil. But if you get a service in exchange for ads then yes, in this business transaction it's you who's being sold, you are the product.

Whether to see it as good or bad is up to you (after all we sell ourselves e.g. to employers), but this observation is not "childish" or "woke", it's a matter of fact.

Neither Netflix nor Spotify make market dominating utility "media players" that can be used to browse any streaming media.

What Netflix and Spotify do is akin to what YouTube or Apple Music/TV, or even online marketplaces like eBay/Amazon/etc does. Personally I'm not that keen on the "recommendations" most seem to generate but it's them analysing what you've interacted with on their platform and showing you things they think you might be interested in.

Google controls the browser, search engine and ad network - all of which interact in some way with third party sites the user actually wanted to visit.
