It always feels like I'm working against the OS now that the OS philosophy has shifted to being all things to all people.
If it's Windows or macOS, it wants to advertise to me, or prevent me from launching certain apps or features.
If it's Linux, it's trying to shift me into some ill-thought out use pattern. This is fixable, but at a significant time cost customizing things. Actually, I'm being unfair to Linux, environments like XFCE pretty much stay out of your way. But I don't like where the mainstream DEs are going.
