False dichotomy. You have also offered this with zero supporting evidence. How do you know what the goal of the algorithm is? Is that your opinion? And what does it even matter what the alleged goals are? Should we not prioritize results over stated goals?

Isn't the actual goal of for-profit enterprises profit, and if serving ads and accumulating data nets profit, isn't that better achieved when people spend more time engaging?

Anyway, good effort on the PR.
