GPL license for modified discourse for own website

Thanks.

How about the case if developer makes a larger web application with discourse being part of it, e.g.,

  • a social media app with a forum component
  • use discourse differently from a typical forum app, e.g., use it as a comment section for an article.
    will the full app be mandated to use GPL.

I’m aware discussions here is not legal advice, but appreciate some early feedbacks.
