What is a responsible design/web application? It is just being responsive and accessible?

I came across the interesting term "responsible applications" used in an article, which proposes that an application that is responsible to the users is one that both responsive and accessible.

It could be argued that a responsive website caters for a range of devices and interactions, while an accessible website caters for users of different abilities and therefore both aspects encourage diversity and inclusion.

However, for a design to be truly ethical, and for the resulting application to not be harmful to the user, is that enough to cover all the bases? Do we need anything else?
