>People complaining about dark patterns with buttons are missing the point. More than one colored button is bad with all current design.
I think you might be missing the point honestly.
Making all buttons to look like buttons is a design choice I like. I would even venture so far as calling it objectively good design from a usability standpoint. People may disagree.
Opinions about how many colors should be in buttons are in any case highly subjective.
Perhaps the problem is the concept of a default button. The practical application for it is simply to push the user to the company preferred path rather than provide a choice.
In any case if one button is the more common choice it can be indicated by position or by a more subtle way than making it appear like there is only one button.
