Yeah, team orders are fairly lame, but it is common enough in modern F1, and as long as it's not egregious enough to result in a blue flag, nobody really cares anymore. I'm a Valtteri Bottas fan from way back and I can assure you that it's not behavior that is unique to Red Bull.
I would have thought the way the race director restarted the race after Latifi's spin a few laps before the end, in a way that predetermined the race outcome, was what you were referring to. There was always going to be someone pissed off about that situation, although Masi went pretty far in a strange direction and managed to piss off the maximum amount of people. If he'd red flagged it immediately, that would have given a free set of new tires to everyone and blatantly handed the race to Hamilton instead of Verstappen.
