"Why do people still use Chrome?"
Because some websites won't work right with other browsers? I don't use chrome myself, and put up with a lot of websites not working very well although I do use a lot more profanity than I used to. My perception is that between security issues, javascript, vendor misbehavior, government misbehavior, and miscellaneous lunacy, the Internet is rather closer to total chaos than most folks realize. But maybe I'm wrong. I am sometime.
