It supports a company selling linux laptops, and they make sure everything works out of the box, and provide support. Pretty much the same reason to use their OS, which is basically just Ubuntu + drivers. It should all "just work" which is exactly what a lot of people expect from a laptop.
If you have a desktop system that's giving you problems in linux because of incomparable hardware or crappy drivers it's a pretty easy to find what component is working well for other people and swap some parts, but laptops are such a pain I don't even want to open one up if I can help it. It sounds like System 76 works with Clevo to put together certain builds they might not offer normally. Why risk getting a similarly spec'd Clevo only to find out it's got a different wireless chipset or GPU variant and now you're stuck with a bunch of of problems to try to work around.
