I believe the quoted paragraph in Scot's post is true to a greater or lesser extent for every artist in any medium whether they have the courage to admit it or not.
We can all spot a deliberate, straight swipe but an exact determination of when influence becomes swipe is impossible to define. To my way of thinking, whether making a definite swipe or just taking an influence from another artist, the important thing is to give due credit. I have always made a point of listing my influences, and as Eric Nolen-Weathington will attest, I insisted on having the ‘influence’ section in the Modern Masters book, because I believe so strongly that we are all part of an evolutionary continuum-- nothing originates from a vacuum. As I have said elsewhere, anyone who thinks an artist is original is simply ignorant of their influences.
The whole ‘swipe spotting’ thing has grown purely because of the dishonest handful who swipe other artist’s work but blatantly deny it. I had the misfortune to have one particular Walter Mitty hitch a ride on my coat-tails some years ago and since that time he has made the most ludicrous and pathetic justifications imaginable, some attacking my reputation, rather than simply being man enough to tell the truth. He and others like him could learn from Scot's example.
It was a genuine pleasure to read Scot’s frank honest analysis. Not only because it offers insight into the thought process and motivations of an artist (which is true for most if not all artists at some point in their development) but also to know that there are folk, like Scot, with honesty and integrity, still at work within the industry.
