I get that Elasticsearch wants to run their own company, but I really have no sympathy for their arguments here. They released open source software and now are mad that it is taking on a life of its own that they don’t 100% control. That’s the whole point of open source as far as I’m concerned, other people can do stuff you might not have expected with your code.
Now they’re making it more closed going forward, which is fine and is certainly their right to do. But this argument is so bizarre, instead of saying that we tried to do this open source but unfortunately it makes it too difficult for us as a business so we’re closing things off, they’re trying to spin it as they are the true, good defenders of open source fighting against the forces of evil by closing off their licensing further.
