Grafana, Loki, and Tempo will be relicensed to AGPLv3
All of the most important software of our lifetime is going through this relicensing effort as the creators attempt to capture the value of what it enables. This is not some nefarious plan to screw over the community. It's a very measured and thoughtful way to ensure the long term progress and continuity of these projects. If the core companies maintaining them did not do this they would eventually die and these projects would slowly rot. Hopefully over time rather than having everyone choose their own licenses we end up with some form of standardisation.
