Very good point. The point I got from the author was that it would simply be nice to hear a bit of gratitude for "how" they are able to be there. True, they are there to be recognized by their peers, but they often thank families, executives, make political speeches, etc. So, while I agree with you on the whole, I wish they would realize that they should simply thank their peers and exit the stage --not continue to push their beliefs on hapless viewers.
Most of them do say "thanks, thanks thank bye!" some thank their relatives for getting them into acting. A very small percentage do the political thing...
