To put it simply, people nowaday spoiled with choices while they wanted needlessly to be served what they want.

Back in earlier gaming era (90s and 00s), console exclusive and PC exclusive is a thing and no one even complain, people back then accept the fact that mostly game are only available on Consoles, and those that released on Computer are mostly Online/LAN games or MMOs, This trend continue until late 00s where some of console games get ported to PC because there is demand.

Pushing through 10s, PC is relevant as the cost of the system is almost same (or even cheaper) compared to the console, back then you can build gaming pc out of dell optiplex and slap a 750 or 750 Ti and you'll get something similar to PS4/XONE performance. Once it gets to late 10s where entry price of PC is a bit high (you can thank Intel for keeping re-releasing 14nm up to 6 generations and then Ryzen came) if you want to have more FPS and prettier graphics on PC.

Now in the 20s, we have tons of hardware variation that can play a game ranging from components from 2014 that still holding up although struggling to get 30/60fps, to something workspace component that can run games 144 FPS+ on casual games. Heck you can even run game without owning the hardware by streaming them (GeForce Now)

In my opinion these people probably those who back then owned consoles and jump ship to PC and expecting same treatment as console player. And of course you cannot guarantee A PC (without specify its components) to run games as much as I encountered some kids tried to run AAA games on their school laptops that had Intel Celeron with dinky 4GB of RAM, while on console it is definite to run as it was mean to run games.
