Just to clarify, the Timescale License was originally announced in December 2018. At that time, we didn't "relicense" any existing Apache-2 code, we just said some future features will be licensed under the TSL rather than Apache 2. Many people over the past year+ knew that we were working on a distributed version of TimescaleDB; a common question was whether the distributed TimescaleDB would be paid-only (like some other time-series database alternatives) or whether it would also be free. This announcement was meant to say: Yes, multi-node TimescaleDB is free, not paid. So there wasn't any _new_ license announced today; just that multi-node TimescaleDB would be released under the TSL rather than as a paid-only option, which many of our users had assumed.
