Below I have listed a Business use case in which I have noticed a profound problem:

1. I create a marketing form with a purpose and an associated topic

2. I submit the marketing form and click on the purpose and the topic

→ Output: Purpose is opted-in, Topic is opted-in

3. I submit another marketing form that also contains the same purpose and the same topic, but only click on the purpose (topic unchecked)

→ Output: Purpose is opted-in, Topic is opted-out (updated from opted-in without an unsubscribe)

Problem: although consent has already been given, it is automatically withdrawn by submitting a form with the same topic, even though there is no active unsubscribe. This in turn can lead to opt-ins being lost, even though they still want to receive communication. (e.g. in a contact form where a newsletter checkbox is optional)

Usually if contacts do not want to receive any emails, they would actively unsubscribe from the communication via the unsubscribe link in the mail in the Preference Center. Now, the consent is changed via every form submission regardless of wether it is a subscription center form or a marketing form that contains the same topics, which I see as a logical error.

Desired functionality: When submitting a marketing form, it should be checked whether an opt-in already exists for the unchecked purposes/topics provided. If there is an opt-in, this should remain in place or at least there should be the possibility for users to prevent automatically opt-out the contact when not checking the checkbox. An opt-out should only be generated by an unsubscribe of a purposes/topics in the Preference Center.
