We are now at the point where the average PC user can configure linux to their liking but it takes a windows sys admin with strong domain knowledge to configure windows to their liking. Im a windows sysadmin(pretty shit one but still) and I struggle to remove a lot of the w11 features and have been unable to get it working how it used to.
Average PC user doesn't even know what an OS is. All they know is clicking certain icons. Newer GUIs are designed to be anti-intellectual. It has started to gain speed with iPhones and has been consistently worse.
What you remove/configure also depends on what you expect. Windows and its ecosystem is GUI-first so I can do most of my customizations using a GUI app like Winaero Tweaker. I can use Powershell to remove certain Windows components too. It usually takes 1 or 2 hours and it stays as it is even with semiannual updates.
With Linux systems I spend much more time to bend it to my wishes but the whole design philosophy is off. Most of the configuration doesn't give proper feedback. It sometimes half works. The API churn rate in Linux world is higher (a lot lower with KDE, to give them the credit). Package management is great. However you don't actually get to choose. Browsers use GTK APIs and cairo, I dislike the libraries (especially the font rendering) but have no choice unless I want to port browsers. I dislike CSDs, again no choice especially with how Wayland turned out (basically CSDs are default, apps opt-in to SSDs). Many things that can have good GUIs are terminal based. The existing GUIs break often. So it quickly turns into me fighting the basics.
I learned a lot from trying to make Linux my desktop and debugging driver issues from ATI cards (anyone remembers fglrx and editing Xorg config?) to Nvidia ones. I used Linux as my primary desktop between 2008 and 2020. I developed many software on it and still earn my living from embedded Linux stuff (I use WSL2 nowadays). However more I look into Linux's "engineering" more I hate it.
If I really want it, I need to spend some serious development time creating a more Windows-like OS out of Linux starting from libc and go up. I dislike almost every library I read the source from Linux world, especially GNU and GNOME ones. I like Qt and KDE's software architecture but the anything below (maybe except systemd) is off. Maybe Redox is a better target for this effort but I need a working system for my desktop now.
