ejmartin discusses on his website the Nikon approach towards RAW compression, which "is lossless in that the image is still encoded without loss of visual information", while Borg is discussing the Sony way of doing it. My levels of knowledge are insufficient for a verdict concerning the validity of Borg´s arguments, I suppose careful testing could show whether there is a point to it or not.

No, ejmartin discusses on his site that "lossy" compression is a clever use of information theory to save space by eliminating redundant raw levels, something that Iliah Borg doesn't comprehend.
This is not the first time that ejmartin refuted Illah Borg's claims. Have a look at 14-bit vs 12-bit thread,

Basically people refuting Iliah Borg in your thread (such as DSPographer) are more credible than him.
