Privacy concerns for the most part. Also for better desktop performance and less bloat on my existing hardware. I was not going to buy a whole new laptop just for macOS, and also gaming on macOS is not nearly as viable.

I would like to somewhat dispute this idea that all Linux users enjoy fixing problems for entertainment. Don't get me wrong, I can and do solve problems in Linux, but once I have a setup that works, I just use my machine normally rather than constantly tinkering with it.

As for how I went about the switch, fortunately, my laptop at the time had 2 NVMe slots, so I installed a second drive and dual-booted between Windows and Linux for a while until I had set up replacements for all the programs that I use regularly.
