Consent is what the individual gives, so you give consent for them to use, and it's like, look at the front office, that's where the forms, etc. go. What happens in the back office is you need sufficient granularity so if you chose A, B, and D, but not C or E, then those three would be taken, and that's not happening. The organizations that collect it, in most cases, do not change the habit of the back office system that will allow that level of granularity, so regardless of what you do on consent, you'll either get everything or nothing.
