This gives a very interesting data point to the &quot;open-source&quot; vs. &quot;free software&quot; debate. Normally free&#x2F;libre software zealots would tout BSD&#x2F;ISC&#x2F;Apache licenses as a way to never get back any downstream changes. And yet - cloudflare did contribute back nicely to a BSD-licensed project, in a situation where they were absolutely <i>not</i> under an obligation to do so.<p>In fact, even GPLv2 would not have imposed an obligation to publish changes here, only a super-strict GPLv3 would.<p>One data point of course, hardly warrant a far-reaching conclusion; still - that is something very nice to see.
