Its not about information but about directing the user in this case. Not everything has to be information dense or even convenient. Sometimes you want users to scroll or make them click step buttons. (checkout is sometimes made to have more steps to give users time to adjust to pain of paying)

Agree. Info-dense designs are also more difficult to implement and many designers lack experience in this area. E.g., creating a coherent design system that uses borders instead of excessive padding to separate elements is much more difficult than it may seem.

Agree. I opened this iventions website, hated every second being there, closed it.
