Just received this e-mail from Mapbox
Starting with the next release in July, the Mapbox Mobile Maps SDK will use a new distribution model and an updated version of our core map renderer, Mapbox GL Native. The core rendering library used by the Mapbox Mobile Maps SDKs will be a proprietary build of Mapbox GL Native. The Mapbox Mobile Maps SDKs themselves remain open source under a BSD-2 license.
Moving to a proprietary build of Mapbox GL
With these new releases, the core Mapbox GL dependency will no longer be licensed under BSD-2 but will be a proprietary build and licensed under the Mapbox Terms of Service.
Tasks.org uses Mapbox Maps, and it turns out I’ve been shipping a non-free transitive dependency since April. I assumed the licensing was a mistake (mapbox-gl-native-android #316), but now I see that it was not. I’m going to downgrade the Mapbox SDK to version 7.4.1 for the F-Droid build, which was the last release without mapbox-accounts-android
