I agree with everything you said.I get what Libertine is saying but I hardly think that Kuss would want to be cast as Mary Poppins, Kuss could never have known that he would be completely dismissed and ignored but Remco and others. Would certainly not categorize being part of a 40+ rider roll off as hyper aggressive or overly intelligent. He made lemonade out of lemons when he was astonished to be in the red jersey, He won but Remco also lost, wasn't Sepp's responsibility to alter the media and Remco that he has been climbing at the front for a couple of years, and that his ITT times are not horrible. In the Spanish interview after, he thanked his teammates, named them, and said that the winning experience was made better by doing it w them. So if being polite and considerate is a character flaw, he is certainly really really F'ed up..
I love Kuss and think he is a very deserving winner. Is he the strongest rider in the peloton for this race? Probably not. Did lady luck smile on him when he got into that 40 rider breakaway? Yes. Was he lucky that Vinge and Remco don't ride for other teams? Probably. Has he worked tirelessly for both Remco and Vinge over the years and been a critical component for all their of grand tour wins? Yes. Is he deserving to be called the 2023 Vuelta a Espana champion. Absolutely.
I also love the fact that not only is he the most popular rider on Jumbo, but if you listen to Gerant Thomas, he may in fact be the most popular rider in the entire peloton. It shows that sometimes nice guys do finish first. Hence, "The People's Champion"
