Hasn't "zero manufacturer support" been the normal state of Linux since forever? It's only recently that some level of official support has emerged in limited cases.
In laptops, Dell has been officially making Linux compatible models for years.
There are also smaller, specialist manufacturers that do Linux laptops. System76 is one that springs to mind, though other people have mentioned various others before.
And most of them are similarly riddled with random bugs, like the CPU throttling to hell. E.g. the T480 has a more limiting throttling, because the motherboard can tell whether you hold it in your lap or not, but only on windows - on linux it defaults to the safe bet of being on your lap all the time. It can be circumvented by a python script that regularly overwrites this variable..
