Actually, the idea of hiding likes from the public has been getting a massive amount of positive feedback. And the counter making people addicted, is precisely why they’re doing it. (note: you’ll still be able to see your likes, just not the public)
Bots are not the primary reason for this being tested. Although it would deal a significant blow to them at the same time.
Social media has caused a massive uptick in depression. And it’s pretty much destroying people’s lives socially, and professionally. For example, many modeling agencies out there just flat out will not hire you unless your photos get above a certain number of likes. Obviously the could still ask to see your private like counter. But that’s just one example from a pool of dozens.
It’s going to be interesting to see how this is handled, because as you said another platform would just come along to feed that addiction. But as a service to the public, morally it’s the right thing to do.
But we all know, Facebook and Instagram aren’t exactly notorious for doing something for the greater good of people, above the dollar.
