Clarification requested: license for WavLM-Large pretrained checkpoint weights

Hi WavLM team,

We are seeking clarification regarding the license applicable to the WavLM-Large pretrained checkpoint weights.

The microsoft/unilm repository and its WavLM directory refer to the MIT License in the repository root. However, the Hugging Face model card for microsoft/wavlm-large links to the Microsoft UniSpeech LICENSE file, which contains CC BY-SA 3.0.

Could you please confirm:

1. Which license applies specifically to the WavLM-Large pretrained checkpoint weights?
2. Does that license permit commercial redistribution of fine-tuned, converted, or quantized versions of the checkpoint?
3. Is the CC BY-SA 3.0 link in the Hugging Face model card intentional, or is it an outdated/incorrect reference?

We fine-tuned WavLM-Large for an academic speech-recognition project and would like to ensure that our model card and downstream licensing information are accurate.

Thank you!
