Not listing and/or not emphasizing the core component of your product can lead to confusion and (possibly intentional) misrepresentation. I've seen situations in real life where someone will say "hey this tool is cool, how did they make it?" and another person "oh they used framework X, I think." A good chunk of people will then do their due diligence and discover that it was Framework Y not Framework X... but not everyone. There are some people still to this day, for example, who believe that AngularJS powers Youtube's desktop site.
