If you look at the subtle details when he's talking, you'll also notice things like him doing finger quotations and rolling his eyes a little when he says "sports entertainment" and then with a straight face adds "and / or wrestling", making sure nobody gets angry at him calling it sports entertainment while at the same time making sure Vinnie Mac is happy that he named "sports entertainment" first as a seperate thing to wrestling.
Cena also doesn't get enough credit for putting in effort to improve upon what is usually criticised about him. After that whole "5 Moves of Doom" meme got so popular that it became an achievement in the WWE All Stars video game, he actually tried doing different things in his matches from 2012 or so onwards (huracánranas and even a weird springboard stunner on a regular basis, which i had never seen before) while still finishing with his moves of Doom sequence to keep existing fans happy. With someone like Cena, who never really moved like a natural in the ring, it's clear to me that he actually put in work to get better at this.
If someone like Hulk Hogan was as reliable as John Cena, that would pretty much be the absolute best any company could want out of an employee. Because of this though, it's basically impossible to say if John Cena is unironically a CCP supporter or not, because even if he was, he would make damn sure to try not being overt about it. I wouldn't be surprised either way, because while he clearly is not a malicious person who wants people Tiananmen squared, a lot of people who spend extensive amounts of time with the high society in red China buy into their narrative points because that is all they are ever exposed to and it's easier to believe what you see with your own eyes.
