I think you'll find that manufacturers with a bit of video history/involvement are much more likely to include features/tools that help with setting good exposure.
So what point are you attempting to make? The content cannot be verified, so who knows where it came from and how it was created, especially since you have a history of faking images to suit the agenda you are pushing at the time.
In a lot of cases raw data is not encoded as RGGB, or encoded using lossy compression (can be RGGB, can be not). In RawDigger there are tools to look at the original data before full RGGB reconstruction.
Many cameras include certain metadata (black level, white level, midtone calibration) in makernotes as a part of raw file. For those few that don't (edit: or we don't know where it is or how to decipher it) we do tests to find the necessary values to scale the histogram.
That was to say that Alan has a point. Raw histogram in RGGB from a lossy compressed / non-RGGB file is as accurate as the full RGGB reconstruction is. There are ways to verify the accuracy, and one can also compare histogram from such a file to the histogram from the derived DNG (using Adobe DNG converter).
He is defending his pallet of tools, trying to say the raw is clipped when it is not. One push of a button in FastRawViewer (highlight inspection) shows how it is.
I think there would be potential to monetize this perpetual motion. Creating an YouTube channel called "Exposure Bumfight" or something like that and have hours upon hours of back-and-forth might well be an underground hit even among people who are not into photography at all. After all, a lot of people get hooked on equally bizarre reality series.
So, if you put forth an argument and someone disagrees by means of a rebuttal, what do you do, personally?
If you do respond to the rebuttal and that person comes back with yet another rebuttal ad nauseam - at what point does nauseam commence for you and is that point the same for all members? I think not because, as a cripple with nothing better to do than to trawl around the internet participating in interesting (to me) discussions, I can continue to rebut a false argument until the sun goes down whereas another member might quit after responding to only one rebuttal.
