Ugh.<p>I was going to link you to the doordash version of the logo, but they pulled it all from their site.<p>The purpose of the logo is mainly to make the site not look weird.    Since they use logos for everything else, having this huge blank space would look odd. So they shoved something there.<p>As for the legality, under things like nominative fair use, doordash can only use as little of the trademark as necessary  to identify to consumers.  In this case, that is likely the words but not the symbol.<p>So if they <i>actually used the symbol</i>, they would be in trouble.<p>(In essence, in-n-out will argue this both ways.
They will argue using a fake logo dilutes their brand, and that doordash can&#x27;t use their logo if doordash tries)
