The licensing, at least in the large, is not the least bit unclear to me. And neither does it appear to be to you since you summarized it earlier. But the file by file examination, as part of an Apache release, has great value.
What you fail to understand, or at least appreciate, and by failing to understand this entirely miss the Big Picture about Apache, is that our releases are the way we benefit other projects. It is the scrutiny and review we give to code, as part of our pre-release reviews, that make it much safer for others to use. Our releases procedures are focused on preparing source distributions that others can use, to build derived products from. We carefully review file headers, produce aggregated LICENSE and NOTICE files, carefully verify that we can build from our source tarballs, etc. Our due diligence reduces risk and raises the comfort level that others have in using the code. That's what Apache does. We don't just slap an Apache License on things, hold our nose and toss it over the wall.
You seem to acknowledge this when you express impatience that we have not done this further review work already. LibreOffice acknowledges this when they merge in code form our releases and rebase their entire product on the released Apache code.
As for your assertion that the "ASF chose to take on the role of stewardship of this code". You are in error there. There has been no vote on this. SGA contributions do not require a vote. A release requires a vote. That is when we make the greater claims, as I have explained at greater length previously.
As for this article, the inaccuracies are legion, and I've rebutted several of them in another comment. But life is too short to waste time with a pedantic correction of every error.
