I don't think current trends in photography hurt anyone. Crap is crap and good work stands out over the junk. Art, regardless of the medium, will always be a subjective experience and whatever moves people will sell no matter how it was created. So, regarding the argument that it hurts true creative art, I wouldn't buy into that.
A true artist chooses a medium which suits their ability to produce their work. It is not necessarily going to influence the audience about their like or dislike of the finished product. We need to get over the resentment of new creative techniques and get on with the business of making pictures to express ourselves.
Acoustic guitar is a beautiful instrument. Electric guitar is also beautiful. In the hands of a master both produce excellent results. There's also a lot of people out there with electric guitars. But you are not buying all of their records....because not everybody with an electric guitar is good enough to make records.
