Exactly.
I'm not sure why some think it's "hides and floor sweepings"
If you don't WANT it , don't buy preground meat, but don't make up things about it that simply aren't true.
My brother worked in a a traditional (European style) butcher shop for many years. He says some of the trimmings they are talking about using might be what a butcher would grind into sausages, but some might be what they sent out to be rendered/tossed. Either way, he made a face when this "pink slime" came up... and he is not squeamish. It won't kill you... But it's more suited as slop and we eat it up don't we?

So people pointing to them to say "hey, they don't have great labeling, so end of discussion" doesn't make much sense to me.
