I can barely run steam and the games I bought on steam at the same time, which is required for most games. Steam disabled certain features and bloated the software – their launcher takes more resources than actual games. AAA games. (From a decade ago, but still.)
Other launchers might be garbage but the bar seems to be pretty low. Only thing anyone can say is “get a better computer” because in their mind that is a great rebuttal to “why is a game tied to a launcher which takes up 4x as many resources as my entire OS?”
Look at the sports with systemic ad presence vs sports where it’s all “grass roots.” (The grass roots ones are mostly gone.)
Most top sports are incredibly expensive to keep running and the ones that become infested with ads are the ones that stick around for us to enjoy. If you follow less popular sports you’ll consider yourself lucky to bring in ads and sponsors.
