As far as I know, there are indeed several social media that are trying to create their own crypto, one of the most famous of which is Facebook. But what happened was, failure. Yes, because it was hindered by several problems and because there were several regulations that affected it. Making crypto for social media is not that easy, especially if they are already well-known, there will definitely be pros and cons, and will be associated with various regulations. And if one day it actually exists and does well, I don't think it's a big deal for crypto. In fact, it might attract more public attention.
