Actually, to me the MS statement is the most illuminating and I'm guessing that Canonical is getting some grumpy calls from Microsoft.
This is the last part of the Microsoft statement:
"Our terms with our publishers allow them to provide customers with implementation and technical support for their products but restricts them from using contact details for marketing purposes"
Canonical then tells us that this person was a Sales Representative, and it is clear from the content that this is a message aimed towards selling. Canonical has broken Microsoft's terms. That said, I can't see where that legal restriction is (e.g. can't see anything like that in https://azure.microsoft.com/en-us/support/legal/marketplace-...).
