Has anyone cleared the corporate logo use with a lawyer? In particular, keep in mind the following regarding the Apple logo:
# NOTE: The graphic image associated with the Apple logo character
# is not authorized for use without permission of Apple, and
# unauthorized use might constitute trademark infringement.
I am aware of that. As the developer of Devicons I am not claiming any rights upon the logos.
Also take a look at the note at the very bottom of the page:
Note: All brand icons are trademarks of their respective owners. The use of these trademarks does not indicate endorsement of the trademark holder by the author, nor vice versa.
