"The community now understands that the original concept of open source has to be fixed." Well, how lucky for the community that a wise startup came along and fixed open source. I get that open source business models are hard, especially in an increasingly commoditized space like databases. Still, it rubs me the wrong way when a business wants the goodwill of open source, then tries its hardest to bend the rules in i…
Why does one have to make money with open source? Why does that have to be a goal in and of itself. Are people going to take your stuff and not contribute back? Possibly .. that's why there's the FSF/Stallman and GPLv3 argument. Out of curiosity would the GPLv3 at least force providers like Amazon to release any modifications they make to FOSS stuff to turn it into a hosted/managed service? With things like Apache/BS…
Aurora is absolutely a fork of MySQL; they're careful never to explicitly admit this in most of their documentation and marketing but their CTO's blog[1] links to a paper that mentions "obtaining significant throughput improvements over the base MySQL code base from which we started," and given how tightly they mirror MySQL with things like version numbers and goofy configuration flags that only exist for backwards-compatibility reasons, it would be hard to believe they built it from scratch.
GPLv2 and v3 both allow this because they only require source modifications to be made available when the resulting program is distributed outside one's organization. Since the public only ever talks to an interface and never obtains the binary, Amazon doesn't have to redistribute. This is not true of the AGPL, which has additional redistribution requirements meant to prevent (what copyleft activists perceive as) this kind of abuse.
There's an argument that since Amazon's changes are focused around integrating the storage layer with their particular infrastructure, the general public would find their changes useless even if they were to be distributed. Personally don't think this is terribly relevant to the larger discussion around licensing, even if it's true.
