Yeah, I recently had to make something commercial where I didn't think attribution was going to be possible, and I knew that SA wasn't going to fly. I figured I'd check out Wikimedia Commons but found it very hard to find truly public domain images. Though there might have been usable pictures available, I ended up just going out and taking one myself because the search wasn't really practical. I also think a lot of people of the current generation probably don't think that much about licensing and copyright and don't realize how many strings they're attaching to the use of their image when they upload it, when my guess is that for most people, one of the CC licenses like CC-by-SA is essentially the same as releasing it into the public domain (for them), but of course it excludes it from inclusion into any non-CC works for likely over 100 years.
