airbyte-python-cdk has a dependency on `Unidecode` as found here: https://github.com/airbytehq/airbyte-python-cdk/blob/main/pyproject.toml#L82 Unidecode is licensed as GPLv2+ which is a strong copyleft license. https://github.com/avian2/unidecode/blob/master/LICENSE I recommend either relicensing airbyte-python-cdk or replacing this dependency.
