The code under discussion has nothing to do with forcing anyone or anything to the top of a feed. It’s entire observable effect is to _measure changes in engagement_. Any use beyond that is speculative.
However, if you believe that it was to be used as part of a system for increasing engagement, then you are asserting that it is a system with no control groups, which is a stupid mistake that wouldn’t be made by an undergraduate taking their first statistics class. They wouldn’t make that mistake even on the first day of that class, because they took a class in statistics in high school!
