Corporations are leaving their names off the logo. Part of it is just a shell game in hopes of deluding consumers that the product isn't really corporate. (Hint: most products that aren't corporate don't have a logo.) But mostly what it does it make it harder to connect the logo to the owner, if you don't already know whose it is. You see a logo on a thing you like and you want more -- how do you find it? You see a logo on something that pisses you off -- how do you know who to blame? Search "thing with a red circle and yellow circle on it?" Yeah, right.
