This is clearly because most people don’t know what a linear raw looks like. I had this issue for a little bit as well tbh until I started to dive into a bit of research. Most “professional software” hides the linear raw.
Lightroom for instance behind the scenes applies not only a tone curve but also a contrast curve, contrast slider, blacks/whites sliders, as well as a exposure compensation. It is absurd. I can guarantee Lightroom users while culling toss out perfectly fine images due to all of these hidden adjustments which force them into trying to compensate with absurd extreme use of highlights and shadows sliders that they never needed to touch to begin with causing halos and other nasty artifacts.
After I learned how to I was able to reverse the lightroom hidden stuff and get much much better results. You know something is wrong with the software after you reverse all the hidden stuff you end up with a auto generated reverse contrast curve, neg contrast slider of nearly -50 and a -1 exposure on your image.
At least capture one gives you a linear raw if you want it but still has halo and artifact issues if you are not careful.
This is why I think people get confused they are use to hidden adjustments software is doing that it should not be doing.
