the thing with Pogacar is that the vast majority of fans will defend him, there is no nationalism at play at all like there was with Armstrong or Sky/Froome, where they're blindly supported by fans from their country and then everyone else cant stand them. i've never seen anything like Pogacar in this sport. the normie fans will go to great lengths to defend him. i saw someone saying how his Worlds ride wasn't that crazy because "he had a bunch of UAE team riders help him" and it's like...not really, Sivakov barely took 3 weak pulls for him. but then this becomes the narrative somehow.
Pogacar certainly has a lot of things going on for him - kind of a traditional career trajection with good junior results (lets not open the discussion again though), unlike Armstrong in GTs and unlike Froome in everything. Then your nationalism super-fandom argument certainly also is true.
Armstrong was also known as a narcissist before he was found guilty of doping, Froome was not the epitome of sympathy either, Pogi so far can hold the smiling friendly superstar image well (and while I think he is indeed quite likable, he for sure is also a cannibal if it comes hard to hard).
But biggest thing is probably that Armstrong had this TdF-only approach to cycling (at least when he was a superstar) and Sky more or less as well, sprinkled with their anticlimatic way of riding. Pogacar tries to go for a complete palmares including one day races and rides, without doubt, quite spectacularly while doing so. Fans like that.
I also think it served Pogacar well that he has this small spots of being human - like MSR or being beaten by Vingegaard in the TdF twice.
Where the three are not all too different is the communication on why they are so good. Armstrong - I just bust my ass off 6 hours on the bike, Sky/Froome - marginal gains, Pogacar - Zone 2. Three concepts that obviously every pro is aware off and tries to optimize. On the other hand, what is a winning rider supposed to say anyway, irrelevant of doping or not? If its something that is unheard off than there is (a) no gain in revealing and (b) it might be illegal or if not then soon to be illegal.
In general, I am still not sure if next year at the Tour Vingegaard will not again keep the upper hand. I mean, this guy was in ICU less than 3 months before the start. That certainly was worse than Pogi's wrist a year before and arguably he was still closer to the win.
