Yes, Facebook is a benefit. Among other things, it gave me React which much of the modern web is built on, and React Native, PyTorch, GraphQL, Cassandra, Presto, and RocksDB just to name a few.

The question is, what are billions of people doing on Facebook if it's harmful? I don't know. My daycare sends me updates, my barbershop tells me when they're closing and I used it to sell my fridge.

This hole Facebook irrational hate is ridiculously overblown. It's an app, and compared to things like TikTok that is essentially a Chinese psy-op, it's really a great product.
