Isn't it funny that literally all the other vendors do support compressed Fuji RAFs?
I wouldn't know about "all the other vendors", and I recon that 'support' is something that's open for discussion if Raw conversion quality is factored in. Maybe it's something as mundane that they first need to buy some of those cameras to do the color and lensprofiling, and Fuji won't help them with that. I don't know, and neither do you, just speculating.
And (improved) support for Canon mRAW / sRAW and Nikon RAW M (and RAW S for D5 and D500), was only just added with version 10, so it's not that they are singling out Fuji.
Cheers,
