The morality of using dark patterns presents an ambivalent dilemma. Are there some guidelines or the framework when the business need doesn't correspond with users?
Example
Dark patterns- preset when registering, disruptive popup when using a product
I find the usage of dark patterns a very interesting (and complex) topic.
As it is a very broad area I would start dealing with a concrete example.
The newsletter example could be approached with the European Union GDPR (General Data Protection Regulation). A well known email marketing company offers some information about it: https://mailchimp.com/help/collect-consent-with-gdpr-forms/
This 2020 study about the use of dark patterns after the GDPR is also very interesting: https://arxiv.org/pdf/2001.02479.pdf
