There is a secondary issue on that there is other people being able to craft high quality images with strong compositions without spending the "effort/training" that artists had to use over years to produce them, so they are bitter about that too, but that's generally a minor cross-section of the publicvoutcry tho they are quite vitriolic
Photobashing, tracing, etc there have always been a layer of purists whom look down on anyone that doesn't "put the effort in" yet get great results in a timely manner, these purists will always exist, just like how it was when digital painting was starting, people were looked down by oil painters for not putting the effort in, even when oil painters themselves used tricks like projectors to the empty blank canvas to get perspective perfect images, but that's just human nature to a degree, trying to put down other people while yourself doing tricks to speed up processes
