I intended this in contrast to your point above.

It could mean the algorithm designers have decided that optimising for fun is more effective at increasing engagement than optimising for shock value and conflict.

But, this is a different choice than other social media designers have made. It seems like there is some more wholesome motivation.

I don't think the other social media designers deliberately optimised for shock value and conflict. I think that was a side-effect of a naïve optimising algorithm: short term (i.e. until people just quit the social media platform entirely), conflict and doomscrolling are two of the most engaging behaviours.
