Simply put, I would never allow these dark design patterns into the product if I was the designer, by arguing that it would affect perceived trustworthiness of the company and brand credibility if dark patterns start to become pervasive and the norm across the product. As a professional UX designer, it's my duty to be the voice of the user and I'd put my neck on the line to make sure I voiced my concern before they went over my head and implemented dark patterns. I'll never sign off on it.

The issue is a lack of accountability by designers/PMs who hide behind the company name when these dark patterns are exposed. In an era when companies like Facebook sway political elections through their dark pattern designed newsfeeds, watchdog groups and regulatory bodies need to be created to keep them in check.
