I’m well aware revenue and profit arent 1:1. You’re “source” is a “Google person says they break even” in 2015. I give you graphs showing revenue growing at almost 4x the rate of users since 2015. Are they making 800% more profit, obviously not. But they sure as hell aren’t losing money on YouTube anymore.
I don’t know anything about how that stuff works. But considering it’s on Steam and has no dedicated servers you choose and it’s cross platform would it not have to talk to a lot of different servers simultaneously? Like, I can squad up with my buddies from the UK while I’m in Canada and also have someone on ps5 in the USA. None of them experience lag. Seems like it isn’t your normal every day “net code” most other games would have to accomplish
