Why would they need to beat Meta/Google, and at what game? They just won’t let any other add network work in their app. Voila! You just beat Meta/Google, and they didn’t even compete with them. I guess they could provide some sort of SDK for websites to embed that tracks users, or they could come up with a browser extension that tracks users too. They already have an app that people are freely giving them so much info. Where else could the compete as you suggest? Being a generic ad platform to serve ads not through their app?
