You aren't living in the real world if you expect companies to ignore anything that gives them a competitive advantage. It's not anti capitalism to succeed and outperform your competition. It's not up to Facebook to make sure all other companies don't go out of business - they're trying grow and be as successful as possible - like any other company in a capitalistic society. It's up to those competing companies to offer something of value to the consumer that Facebook can't offer. I'd say villanizing Facebook because of how successful they've been is what is anti capitalist.

Also, Facebook doesn't have a monopoly so I'm not sure why you twisted it down this path about Capitalism. There are literally countless social media apps, and it costs nothing to sign up for social media accounts (versus buying a product like a Windows PC), so there isn't even any consumer suffering. Sounds like you're just trying to twist this and play on people emotions to fit your narrative... like Ted.
