They would have to triple-quintuple-backflip-down on "open." So, maybe? It depends on how much value is being created besides the code, in squishier parts of the business like service, support, pricing models, marketing, and so on.

But it's moot, since Apache Lucene is part of the Apache Software Foundation and has much stronger promises about its licensing and governance. Which is not a small reason why Lucene is the de facto standard for search technology.

Yeah. It just seems to say something if the license they are insisting is the "spirit of open source" that everyone downstream of them should be okay with... they are counting on not having to deal with upstream...
