I think the intention is to decrease the opacity of 'free' services, with the awareness that most people using most free services don't or can't know what happens with it and what is collected. Money is not personal data, likewise almost anything else is not personal data, and there should be more legal protections in llace imo to protect a naive person's ability to limit the propagation of it, or hold companies accountable. If most people knew how any givem system worked, then software engineers wouldn't make as much. It's not a clear cut transaction when the cost is "any amount of data we can collect about you and sell to anyone for any price in exchange for this specific service we provide amd cam take away at any moment". That's a bullshit transaction.
