Not much you can do about software bloat but I have a different problem, in the form of an art director colleague who seemingly doesn't care about making images as small as possible.
OK, so I get that pictures need to be of a certain quality for print, and that Photoshop files with layers and cutouts are going to be bigger than simple jpegs, but they really don't need to be that big. Quite often, I will open pages that are loaded with images of a high enough quality to print as an A3 poster, scaled down to just a few cm wide, and/or cropped so only a small part of the whole image is being used but retaining the whole image in the file.
This wasn't so much of a problem when we were office-based and sharing the same servers, but now we're all working from home and I'm on the world's shittest internet connection...
Some people seem to take the concept of unlimited storage as a challenge.
