I don't claim that anyone has to like ads. Only that when someone self-describes as an "NBA fan", that sounds like they're saying they're a fan of the NBA overall. When in the next sentence they complain about ads, it sounds like there's an assumption that the ads are encroaching
on the NBA, whereas they're an extremely deliberate action
by the NBA.
If someone said, I like watching basketball games but I don't like watching ads, that sounds different to me.
