But I did expressly consent.
When I installed the SoundCloud app and it told me by continuing I agree to them sharing my data with their 954 partners.[1]
1. I’m not even joining. When I mostly recently installed the SoundCloud app - for the first time on a new device, that’s what’s it said: 954 partners. How can anyone reasonably understand what it is their agreeing to in that scenario.
This is the important point. You need the right to not be discriminated when you withhold your consent, otherwise your consent is effectively meaningless, as it is forced on you by your impossible bargaining position. This is one of the central pillars of the GDPR without which it wouldn't work at all. Be advised to make asking customers for consent that doesn't directly benefit them illegal as well, lest you risk creating another wave of malicious cookie banners.
