> As we know,[The Apache Software Foundation bans the usage of Facebook
> BSD+Patents licensed in Apache
> products|https://www.apache.org/legal/resolved.html#category-x]
> The Facebook BSD+Patents license includes a specification of a PATENTS file
> that passes along risk to downstream consumers of our software imbalanced in
> favor of the licensor, not the licensee, thereby violating our Apache legal
> policy of being a universal donor. The terms of Facebook BSD+Patents license
> are not a subset of those found in the ALv2, and they cannot be sublicensed
> as ALv2.”
> Weex-Team have heard the news and we decide to remove Facebook Yoga
> with its additional Facebook BSD+Patents license. In order to release the
> next version as soon as possible, we will create a new LayoutEngine based on
> [the Google 's Flex-Layout|https://github.com/google/flexbox-layout].
