CS has always needed a GPU.

CS:go required anything DX9 compatible with 256mb VRAM. Which would be an NVidia 6600, a midrange GPU from 2004 - around the time CS Source was released.

CS2 minimum spec is a GTX650. Which is a mid range GPU from 2012, around the time cs:go was released.

Something of a pattern there…

If CPUs didn’t have integrated GPUs, this whole “cs is CPU dependent” thing wouldn’t apply, because you would STILL need a GPU.
It’s just that intel bundled a barely passable GPU alongside the CPU.

TBH, I think you are missing you’re argument.
You should be arguing that there is no way to play cs:go now that cs2 has released. Meaning a potential hardware upgrade requirement.

That is a bummer. That’s pretty shit.

But it is NOT enshittification.

That does not claw back value/money from customers to valve or its investors.
Unless you can show me, beyond reasonable doubt, that Valve is making money from giving away CS2 for free to anyone that has purchased cs:go through the requirement of a hardware upgrade.
Until then, this is not enshittification.

Is it shitty? Sure.
