title: Is iText 5.4.2 open source?
body: <p>I would like to know whether iText 5.4.2 is a open source. I know it is described here well:</p>
  
  <p><a href="http://itextpdf.com/terms-of-use/index.php" rel="noreferrer">http://itextpdf.com/terms-of-use/index.php</a></p>
  
  <p>But I am confused as the page also says this:</p>
  
  <blockquote>
    <p>Buying such a license is mandatory as soon as you develop commercial
    activities distributing the iText software inside your product or
    deploying it on a network without disclosing the source code of your
    own applications under the AGPL license. These activities include:
    offering paid services to customers as an ASP, serving PDFs on the fly
    in the cloud or in a web application, shipping iText with a closed
    source product.</p>
