I have seen an intriguing article by logodesignlove on polluted logos with trademark or services mark logos. And I can’t agree less.
I completely understand and the argument of visual pollution that occurs on the brand material at the expense of the security of cross-border legal rights of the brands (corporates in this case). But these logos go to places where brands might not even be aware of and these logos are their own only safeguard. They exists to remind the legally aware (or anyone with some self respect) that they just have to sit in front of the drawing board a bit longer. There can be set-ups offering completely different (see below this yogurt shop in Central London feeling Googlelish) or competitive services-(ie Goojje Google Knockoff Surfaces In China)
