I am not sure if this is part of the Bitnami Helm Chart Fiasco, but they seem to be changing open source projects from Apache to BSL.
Was looking at chart-syncer, and found: https://github.com/bitnami/charts-syncer/issues/307
And it depends on some tooling from VMware, which has the same notice: https://github.com/vmware-labs/distribution-tooling-for-helm/issues/132
Not that I'm surprised, just stumbled across this.
