You have it reversed. The celebrity endorser is the platform. FTX has no platform, they have money and can buy commercial time. Larry David has his own 'brand', and people like you and I have positive feelings towards it. His mere appearance in an FTX commercial is him lending his platform of positive feelings we all have for him over to the brand of FTX, so that we may associate those positive feelings toward them. That's the endorsement. Even if he said, "FTX fucking sucks, and so does crypto!" in the ad, people would think, haha that's so funny, did he really say that in a commercial?! And the next time they think about crypto they remember their jovial laughter at that dumb ad and "FTX." I also don't care that he endorsed them and don't think he's at all responsible for people losing money in crypto.
