I strongly disagree on entertainment, what appeals to a specific person is a function of that person and the skill the performer has in the aim to hit that spot.

A performer, no matter how more talented that person is, will deliver a worse performance if they are trying to aim more broadly.

Whereas with news the issue is that news died when they optimized for ads/engagement, but that is fundamentally why Facebook, Twitter etc are all terrible. The interests of the user and the interests of the creator are mismatched.
