My first impression for anything on YouTube is untrustworthy spam. Don't matter who it is. It's just the reality of paid sponsorships, and anyone being paid is going to generally talk up the positives, and talk up how much integrity they have. It's not just a YouTube thing either. I assume the same for celebrity endorsements even if it is in an area they are an expert in like sports, since product they use isn't the quality that reaches consumers. Sometimes even the products they use is crap and ends up hurting them. Example Lonzo Ball and the shoes he endorsed.

It's just general good skepticism towards the marketing machine. Nobody is to be trusted when it comes to what they are paid to shill.
