Who licenses Stack Exchange content to end users?
<p>If I take content that's posted on Stack Exchange (or, more generically, from a site that publishes user content based on a CC BY-SA license) and re-use it elsewhere, who is my license from? Is it the author themselves, or is it from Stack Exchange (from the publishing site)?</p>
<p>Relatedly, who has the authority to request that attribution be removed? CC BY-SA provides for the licensor to request attribution be removed, but who has to make that request in this case?</p>

<h2>It’s spelled out <a href="https://stackoverflow.com/legal/terms-of-service#licensing">here</a></h2>
<p>Stack Exchange content and the compilation is licensed to you by Stack Exchange. Subscriber content is licences to you by the subscriber since the licence they grant allows subsequent relicensing.</p>
