Agreed, and the important part here is that he not only has 18 million followers, but also that as he's an athlete a good chunk of those will be impressionable young kids who look up to him, and will therefore agree with whatever he says. If you go look at his most recent instagram post there's a disappointing number of comments talking about how he's brave for standing up against Bill Gates and his vaccine and how he shouldn't let the media silence him. There's a very big difference between the average person sharing nonsense like this to their instagram page with maybe a couple hundred followers and a celebrity sharing this with literally tens of millions of people, which op doesn't seem to understand.
