A logo should promote instant public recognition of your specific business.
If an image is overused in an industry, the usefulness of that image is diluted. There is a specific object that was avoided in this logo, consequentially, the logo is much more memorable and effective for it.
If you want your logo to be memorable, don’t employ images that are exactly the same as everyone else’s in your industry.
