Other people are merely customers. For a customer a game not working as intended is no different than an electric shaver not working as intended. You don't need an understanding, or a modicum of interest in inner workings of electric shavers, you expect them to work.
Insult to injury, people also tend to be more emotionally invested in games than electric shavers, just like any other entertainment medium. Hence they won't just toss one out and get the other, without generating some buzz about it first. I don't see how this is more "spoiled" or "entitled" than customer reviews on Amazon on electric shavers. It's nothing crazy if you feel entitled to things you're actually entitled to, which in this case, an entitlement to a working product gained by paying for it.
But as someone who games on exclusively on Linux, I'm surprised to learn about the outrage. Personally, I'm used to having to debug, alter, or otherwise hack games in order to play them. I'm also more tolerant of bugs and glitches. I've found that I gravitate more towards Early-Access titles on Steam than big "AAA" titles.
I realize most console gamers aren't necessarily technical people, but when did gaming become so entitled? Is the mainstream PC gaming market this spoiled also? I've heard mostly good things about CyberPunk from fellow PC gamers.
