There’s no support, warrantees of any kind, no useful software packages, and everything I would use it for (development, browsing) has a better windows alternative?

I mean… all of these things are just not true. Maybe they were at one time, but they certainly are not now. The amount of support available for Arch alone is staggering.

Also, maybe I’m wrong, but aren’t most software engineers/developers Linux users? Maybe ask some of them why they use it.
