Anytime someone does something good it works out to be advertising for their brand, whether that brand is a company or just a personal brand. Unless they do it in a way no one ever hears about it. In which case no one will ever be discussing it. So your comment is less than trivial, unless you’re implying that it’s a bad thing to do something good if you benefit from it even in the slightest.
