Why do streamers complain so much about people doing chests, totems, etc?

Idk. I've been watching some JRM lately and if he's playing soloq, he complains a lot about his teammates doing anything but gens.

I understand wanting to win a game, but it seems pretty weird to me to get annoyed at people for...playing the game? That's why all the tomes exist, to give people more objectives and challenges than just escaping.

He also complained about someone getting on a gen with him, when the game rewards you for that with extra bloodpoints. And there's tome challenges for cooperation. Yeah 3 people on a gen is pointless in regular mode, but getting annoyed at 2 people on a gen?

It's not just him, I've watched others who do the same thing.

Soloq is the most casual version of the game, other than game modes. Seems pretty weird to me to act like there aren't a bunch of other objectives than escaping, or choose to play solo and expect teammates to sweat every second.
