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.
"You are hereby granted a non-exclusive, worldwide, royalty-free license under Broadcom’s copyrights to use, copy, modify, and distribute this software in source code or binary form for use in connection with Broadcom products."
Feels like it's saying you're only allowed to use it in the future if you use it in relation to some Broadcom product.
