It's not just about the quality, though that is a thing sometimes, but rather about the fact that the wetting situation is being forced against the original intention of the picture.
For those who like the emotional/scenario aspect of omorashi, all the appealing reactions and effects of wetting are absent from the picture, because it wasn't originally intended as a wetting, and sure, some people don't care, but to those who do, it's just kind of uncanny and without any heart.
Edits also have the bad habit of getting saved and spread without some people remembering that they're edits, which lowers the quality of future wetting picture dumps.
