I only briefly dabbled with Arch >10 years ago. But it has always been evident that it is an incredibly powerful distro. The fact that its wiki is so extensive is a testament to how much people are using it. The problem it has always had is that most companies tend to support other ones (Debian, Ubuntu, Red Hat/Fedora, Alpine), so it never really had any corporate love. With Valve's backing, we can see just how widespread Arch could be if it had more money behind it.

Not that this is necessarily a good thing of course. Look at how money has corrupted Ubuntu and Red Hat. All I want to point out is that it can do anything that the most well-supported distros try to do. And the fact that it has done so without any corporate support is a true testament to how powerful it is.
