The fact that apps are "algorithmic doom barrels" comes from unaligned incentives in many of them. "The Apps" reward continued engagement, not finding the best partner. That subscription money disappears if a longer term partner is found, so that's obviously not the goal; regardless of what their marketing/ad department says. "Hook up" Apps, somewhat align but are being be pushed on individuals looking for something else, leading to frustration, dissatisfaction and disillusionment.
