Doesn't Spanner depend on access to globally-synchronized custom atomic clock hardware? i.e. even if it were open source, it wouldn't really be valuable unless you're a data center operator.
As I understand it, it's not a solved problem because there is no silver bullet, but rather trade-offs in every direction, and which solution works for you (including Spanner) is heavily dependent on your use case.
