To answer your questions, people are still on FB today because FB keeps buying its main compatitors buy offering up to 20 billion dollars per deal. WhatsApp, Instagram, etc. How can you compete with that? Well, just say "no" like Snapchat did and cross your fingers because FB would litteraly copy/past your idea. They would use the couple of billions of dollars from your unsuccessful acquisition in order to hire an army of attorneys and to stop you from any legal action. From another perspective, It's very hard to disrupt a social graph because it's very simple and pure. There's no need for it to be duplicated which is why FB keeps winning since they were the first who really created it. The rest is just about ads, billions of dollars, random features/startups and a lot of rich people. At the end of the day, the real value/data of FB is a very simple social graph.
