It's an observable metric. If I don't follow any "return to tradition" Statue PFP style posters, how often should the "for you" tab show you those style posts compared to posts by people I follow, who they follow, and who they interact with?

Pre and post acquisition it was a clear shift. I would only see that style of poster when people I followed purposefully interacted with them. Post Acquisition, I began to get many more anti-immigrant, pro-white, pro-nationalism style posts in my feed.

The use of overweight seems clear to me. You have a feed of items sorted by some score, when calculating scores you have to weight different factors.

Seems pretty clear, and subject neutral
