在 ASF (Apache Software Foundation) 全面禁止 Facebook 的 BSD+PATENTS 後 (「Apache Foundation 宣佈禁止使用 Facebook BSD+Patents 的軟體」)，整件事情開始熱起來了...
簡單來說，Facebook 有意為之，而且不打算撤回這個有攻擊性的授權模式，參考「Explaining React's license」這邊官方的說明以及有人寫了一篇解讀：「If you’re a startup, you should not use React (reflecting on the BSD + patents license)」。
Facebook 內的意見其實也不一樣，像是 Yarn 之所以沒有
在「RocksDB Integrations」這邊討論到 RocksDB 裡 Facebook 所使用的 Facebook BSD+Patents License。
不過因為 RocksDB 最近在換 license (從 Facebook BSD+Patents 換到 Apache License, Version 2.0)，移除了
PATENTS 的舊檔案可以在 PATENTS 這邊看到。
Chris Mattmann 正式發出決議禁用 Facebook BSD+Patents License。(參考最後)
另外也提到了 Facebook 是故意埋下這些限制：
Note also Roy's comment that he has discussed the matter with FB's counsel and the word is that the FB license is intentionally incompatible. It is hard to make the argument that it is compatible after hearing that. Pragmatically speaking, regardless of any semantic shaving being done, having a statement like that from the source of the license is very daunting. If they think it is incompatible, we need to not try to wheedle and convince ourselves it is not.
這個 license 之後應該會有更多挑戰...
As some of you may know, recently the Facebook BSD+patents license has been
moved to Category X (https://www.apache.org/legal/resolved#category-x).
Please see LEGAL-303  for a discussion of this. The license is also referred
to as the ROCKSDB license, even though Facebook BSD+patents is its more
industry standard name.
This has impacted some projects, to date based on LEGAL-303
and the detective work of Todd Lipcon:
Samza, Flink, Marmotta, Kafka and Bahir
Please take notice of the following policy:
o No new project, sub-project or codebase, which has not
used Facebook BSD+patents licensed jars (or similar), are allowed to use
them. In other words, if you haven't been using them, you
aren't allowed to start. It is Cat-X.
o If you have been using it, and have done so in a *release*,
you have a temporary exclusion from the Cat-X classification thru
August 31, 2017. At that point in time, ANY and ALL usage
of these Facebook BSD+patents licensed artifacts are DISALLOWED. You must
either find a suitably licensed replacement, or do without.
There will be NO exceptions.
o Any situation not covered by the above is an implicit
DISALLOWAL of usage.
Also please note that in the 2nd situation (where a temporary
exclusion has been granted), you MUST ensure that NOTICE explicitly
notifies the end-user that a Facebook BSD+patents licensed artifact exists. They
may not be aware of it up to now, and that MUST be addressed.

在「OpenOffice, after years of neglect, could shut down」這邊看到 OpenOffice 要退場的計畫，自於 mailing list 上的「[DISCUSS] What Would OpenOffice Retirement Involve? (long)」這篇。
信裡面完全沒提到 LibreOffice，但就目前幾個大的 distribution 都是安裝 LibreOffice 的情況下，其實會有這個提案就不言而喻了。雖然很可惜，但對整個社群能量的集中應該是好事...
話說回來，Apache Foundation 真的很像垃圾桶，一堆人都把不想維護的東西往那邊丟...
