Pretty simply because I don't want to use MacOS, its terrible window management, quirks and idiosyncrasies. In your comparison, my gripe wouldn't be about the hassle of finding 3rd-party compatible batteries, but about the daily handling of the Makita while knowing the DeWalt to be more ergonomic and better suited to my needs.

As someone who uses Linux, macOS and Windows interchangeably, I'm curious to know what you're using.

I learned to live with macOS, but I also like and use Gnome, which many Linux-only people hate. I tried most WMs on Linux, like Hyprland, Sway, i3, but none ever felt worth the config hassle when compared to the sane defaults of Gnome.
