Eh, Lucent for a while had a logo that was (nearly literally) a sample brush from Painter or something. Painty red circle. And many other logos are pretty much like that and can definitely be generated by algorithms. I'd be shocked if some large logos were picked with far less thought than you're describing here.

Also, offended? It's like photographers getting upset over people giving stuff away, or the influx of rather good amateurs killing their market.

I'm just checking out Tailor Brands, and I can say with certainty the output is similar to what I've seen professional designers offer, on occasion.
