I am sure there will be the odd person out there who likes to hang on to her money beyond what is acceptable and prefers to get something for nothing. Most designers may come across these super stingy clients, who would rather cheapen a good design to save a few dollars; not being able to see the bigger picture. Well, those clients might take any of these logo generators serious and think they are getting value.
Everyone else might just have fun with these. I look at them as an entertaining game, but see value in them as well as a creative tool for my students. It can be a fun start and trigger some more valid concepts. See if you like them.
