I'd have never seen Vampire hunter D on Sci fi channel
and have had that spark my interest in anime. That enjoyment
lead to the dsire to collect cels. I highly doubt that the
creators of my favorite characters(Ryoko, Washu, Ryoga, Vash
etc)cringe at the thought of my personal pleasure in sharing
their creations. And I doubt that cel dealers would prefer
that their market base be a handful of "purists" like these.
Sub, dub, its all personal taste. Most likely its why many
of us are here right now. Its why im back searching for new
cels again(just watched Trigun)
 In fact this is how i look whenever I see new anime at
my local comic shop.
