What evidence?
You should be and you can be better that this. There's a degree of crackpot when someone considers that for a rider to be nice, friendly
and straightforward suffices to uncover a PR plot paid by oil money.
If you really think - which I'm sure you don't - that I would have Pogar as Jesus Christ you shouldn't even be discussing the issue, as you would find it pointless to discuss what are matters of faith. It's much harder though to not invent a strawman to depict your opponents and acknowledge that although Pogacar is friendly, that happens to be in line with a much more scrutinized, mediatic and public-friendly cycling environment of nowadays.
