There's a process for any photograph to be made into a viewable format. If I take a media card out of my digital camera all I have to look at is a square of plastic. If I take a roll of film out of one of my film cameras all I have is a film cartridge to look at. I won't see the pictures until I do something with either one.
I think the post-processing is where it gets into how much is necessary. I find either way, if it's digital or if I've shot B&W film, if I've gotten proper exposures, and I've framed and composed images the way I wanted, I may not have to go beyond processing the photos. I may not do anything considered post, or I might do some, it just depends.
If I got proper exposures when shooting, once the film's developed into negatives, and I've determined exposure time in the enlarger for that roll of film (usually if shot in the same light conditions, etc.), I'd be able to crank out B&W prints pretty efficiently with little of what I'd consider post work (such as to burn in a corner or dodge some detail). I've sometimes just put the media card in the computer, opened it in photoshop and looked at an image - that's probably not what would be considered to be 'photoshopped'. If it looks good, I'll print it, and if that looks good I'm done. Other times I often have to adjust brightness or contrast especially for printing. It just depends.
But much of what I've done is sports and events, and having done that shooting film I know how to frame shots efficiently as things happen quickly. That's where photographers usually need to learn how to get a good shot without needing much post work because there won't be time, they might want the photos like, NOW! There isn't going to be much waiting around for editing to be done, now there's often a picture on a website before a game's even done.
I saw a good bit of misinformation about that Reuters situation, and much of it seemed to have been based on a story in Petapixel written by the self appointed editor of the website (who seems to have less journalism experience than even I do). In that article in Engadget it does clarify that the Reuters photographers were not told to NOT shoot Raw, but to also shoot JPEGs and submit those. I don't think that's unusual to shoot JPEGs for a journalistic purpose. However the Engadget article talks about needing to adjust for exposure being off, etc. which seems misinformed to me. If you're shooting sports you have to know how to get the exposure or readjust it quickly as necessary because there won't be time to correct an entire series of shots much of the time. They expect results and fast.
But what seems to have happened in recent years is many media outlets firing photography staff (then sometimes bringing them back as contracted freelancers). So there seems to be more people with cameras shooting for media outlets who may or may not know what they're doing or who may not have learned the photojournalism ethics that even people like me learned in high school journalism.
