To pull criddell's important question to root-level: How can the trademarked logos (Facebook, Instagram, Github, etc.) be provided without licensing terms?
Basically, you use your own prudence when displaying references to a business (be it with their official branding or with an indirect reference). Of course, many businesses will try to strengthen their brand recognition by insisting you use their official branding or nothing… and only in ways they approve, lest you get on the wrong side of their legal team.
