I love the vendors here..and I always give them credit when possible.  But..bottom line is..without the artist there won't be any art!   If its ok now to get into the charts without giving every credit...then to change it now would be a penalty...and I say that as someone who never gives the charts a second thought when doing a render.
You can argue that without the vendors there won't be any art..but you would be wrong...an artist will always find a medium and tools to create.....and if I pay for the use of something and abide by the TOS or contract that goes with it...then technically I've done my part...anything else is just gravy!
