The UCI have created a monster, simply too big to fail now
I would understand this meme if he was an American or from one of the major cycling nations. But a small Eastern European nation I don't get?
Could it be simply he is very very good? When Pogacar announced himself when he won the 2019 ToC I didn't even know who he was. He became steadily more popular since that day with a spike when he grabbed the 2020 Tour right out of Visma's expectant hands (poor Rogla). Before the 2019 ToC he won the 2018 Tour de l'Avenir before his 20th birthday.
So going back to this thread's OP: It is silly to say he had achieved nothing before he was 20 years old. It is rare any athlete does for various reasons. Greg Lemond is an outlier. Correlation is not causation.
It’s hard to feel too sorry for the majority of the other riders though, they are mostly complicit and seem happy enough to eulogise about the goat
The controlling factor as you allude would be other teams and riders. They would risk legal action by making public accusations against Pogacar that they couldn't prove in court. But behind closed doors there is nothing stopping them making complaints via the right channels - even journalists. But nothing? Surely there are David Walsh's out there wanting to make a name for themselves by uncovering this scandal?
My thought is he isn't doing anything other top teams and riders are not. But perhaps he is a super responder to those methods along with just being a better talent.
