While what you say is in some sense true, we also make fairly large contributions back to FreeBSD as well.<p>Case-in-point: AES-GCM, including AES-NI support, and support for same for IPsec.<p>There are other, more minor contributions, such as the new &#x27;tryforward&#x27; code (replaces what was &#x27;fast-forward&#x27;, but doesn&#x27;t break IPsec).  r290383<p>Or r290028, where we eliminated the performance impact of IPsec (which is now on by default in -CURRENT).<p>I could go on to detail around 30 recent changes to FreeBSD, but I think the point is made.<p>In any case, it&#x27;s a bit more than &quot;bundling it all up and slapping a web interface on top of it&quot;, as you assert, but you&#x27;re not the only person who thinks this way.<p>Your point that we leverage others work is correct.
