It's intentional plausible deniability. By creating the manual step you can shift blame away. It's just like the concept of personal health dashboards which are designed to keep an asymmetry in reliability information from a host and the client to their personal anecdata experiences.

Let's not pretend businesses haven't been intentionally advertising in deceitful ways for decades if not hundreds of years. This just happens to be current strategy in tech of lying and deceiving customers to limit liability, responsibility, and recourse actions.
