Yeah, I agree with your interpretation and that makes sense from Microsoft's perspective. Just one open question that that raises: does a name and employer count as "contact details"? Do Microsoft's terms allow Canonical to reach out to someone on LinkedIn for marketing purposes as long as they don't look them up using the email address Microsoft gives them?

And if the answer to that last question is no, what can Canonical do with the data that's actually valuable to them? If I were given access to a database of sales leads that I was explicitly disallowed from contacting, I would actively avoid even accessing the data to avoid any accusation or perception that I violated those terms, just in case I independently got in touch with those same leads through a different channel.
