At first, probably, yes. But then you start to optimize for different things, because the interests are not aligned : you want "engaged eyeballs" on your service, which may or may not be best for the user. Hence tactics like gamification, notifications, the whole Hooked model, and so on.

Of course we can debate on the definition of what is "best" for the user. Maybe users like and need clickbait headlines and fake news. But to me it's just a softer version of "Maybe users like gambling machines and being addicted to cigarettes"
