Don't know what's confusing about it...  I mean,  I shoot ARW with my Sony,  these work fine with Lightroom and work fine with DxO PhotoLab [1] at least as long as my ARWs are not compressed (it's not that the compression is proprietary,  it's that the compression is lossy and breaks denoising)
[1] Shoot ISO 12,800, process with DxO, people will think you shot at ISO 200; makes shooting sports indoor look easy, see https://bsky.app/profile/up-8.bsky.social/post/3lkc45d3xcs2x so I got zero nostalgia for film.
