  <div class="content">
    <p>For <a href="https://opensource.org/history">over 20 years</a> the Open Source Initiative (OSI) has worked to raise awareness and adoption of open source software, and build bridges between <a href="https://opensource.org/affiliates">open source communities</a> of practice. As a <a href="https://opensource.org/sponsors#sponOps">global non-profit</a>, the OSI champions software freedom in society through education, collaboration, and infrastructure, stewarding the <a href="https://opensource.org/osd">Open Source Definition</a> (OSD), and preventing abuse of the ideals and ethos inherent to the open source movement.</p>

<p>Open source software is made by <a href="https://opensource.org/members">many people</a> and distributed under an <a href="https://opensource.org/licenses">OSD-compliant license</a> which grants all the rights to use, study, change, and share the software in modified and unmodified form. Software freedom is essential to enabling community development of open source software.</p>
