With macOS 10.12 Sierra, Apple has introduced Siri from iOS to macOS. While there are data spillage concerns with the use of data-gathering personal assistant software, the risk here does not seem greater in sending queries to Apple through Siri than in sending search terms in a browser to Google or Microsoft. While it is possible that Siri will be used for local actions rather than Internet searches, Siri could, in theory, tell Apple about confidential Programs and Projects that should not be revealed. This appears be a usage edge case.
