Binance doesn't really care about anyone's status or image but it portfolio and how to make his exchange boom, they knew Ronaldo who has more than 850 million followers across several social media platforms will go along way to make it business boom that's why they signed a multi-year contract just to promote unregistered crypto securities.
Binance took advantage of Ronaldo's large following so they thought it would be easier to increase their market value. that is a good thing for them but not for ronaldo so his image is tarnished among people.
