&gt; I see light of hope in Servo. But liscenses ( MPL? Why not Apache 2.0 ) are a concern for a few company to join and devote resources into it.<p>Copyleft licences are often the best way to go in this kind of situations: thanks to the GPL, Linux remained one until Google forked it for Android. And 15 years after its beginning, there is no fragmentation in the kernel space. 
On the other hand, BSD has been forked many times by companies to build their own proprietary OS [1].<p>The MPL will ensure that Servo is never forked by Google&#x2F;Apple&#x2F;Microsoft into a competing proprietary software, but will remain a free software.<p>[1]: <a href="https:&#x2F;&#x2F;upload.wikimedia.org&#x2F;wikipedia&#x2F;commons&#x2F;7&#x2F;77&#x2F;Unix_history-simple.svg" rel="nofollow">https:&#x2F;&#x2F;upload.wikimedia.org&#x2F;wikipedia&#x2F;commons&#x2F;7&#x2F;77&#x2F;Unix_his...</a>
