FoundationDB acquired by Apple

Vienna-based NoSQL database company FoundationDB has been acquired by Apple, according to TechCrunch.
The details on the deal are sparse; the company has announced on its website that “We have made the decision to evolve our company mission and, as of today, we will no longer offer downloads.”
Here’s TechCrunch’s take:

So. A fast, affordable and durable database company, acquired by Apple. It seems likely that this was an acquisition designed to bolster Apple’s server-side technologies for the App Store, iTunes Connect or iTunes in the Cloud. With millions of apps now in the store and billions being served to users, there is undoubtedly room for improvement in those systems.
