Granted, I've always had these kinds of issues with new laptops, especially when it came to proprietary nvidia or AMD graphics (before AMDGPU) and I agree it's improved a lot, but I still need to tell people that there's caveats with some (especially newer) laptops.
But I always take some time to look if somebody succeed in installing Linux on the laptop I want to buy before. If it means I need to wait an extra 6 months, then I wait a bit.
All the builtin radios, cameras, microphones, and sensors in modern laptops make them ideal for stealing your private data. I already have an untrusted cell phone, I want my personal laptop to be something I can feel comfortable keeping my data on. Because I can't personally audit every chip, that means I need some level of trust, and Lenovo has demonstrated over and over and over again that they cannot be trusted.
System76 is looking into making their own hardware now too so I'm really looking forward to seeing what they come up with in-house.
They do make their own desktops and minis now. I think they use Clevo for laptops, and those do get more complaints here on HN than the desktops (but I think the consensus is they are getting better). They have more laptop models, so making their own would be a huge task.
