GOS is in place to stop the phone overheating due to extended play times of some games. It protects the phone.
As @Glenntech mentioned Samsung have listened and are currently working on a software update to allow the owner further customisation.
Until then if a person wants to disable GOS then one option is an app in the Playstore called Alliance Shield.
The use of different SoC has been the topic of discussion for a while with some people not experiencing issues when using a Samsung Phone with an Exynos SoC inside but some appear to.
My Samsung Galaxy s ²² Ultra 256gb Exynos is working great.
I've also seen posts from people using the equivalent with a SnapDragon SoC inside who are experiencing their own problems.
Samsung have released phone's in the UK with SnapDragon SoC inside.
Im assuming they have an agreement with Qualcomm about the use of SnapDragon chipsets and where and when Samsung deem they use their own Exynos.
I'm using a Fold³ with one inside.
I've also imported a Samsung Note²⁰ Ultra from Samsung Hong Kong before to see for myself how it compared to the Exynos version I also purchased from Samsung UK.
Basically I had better battery optimisation.

The advice I offer is my own and does not represent Samsung’s position.
I'm here to help.
Between this throttling experience, not being able to play my favourite games even at low settings in a S21+ without huge frame drops, and Samsung's terrible client support in my country (México) makes me reconsider upgrading with the brand, a couple of friends have already jumped off the Samsung's ship after many years being loyal customers, its simply not what it used to be.
