I speak enough corporate to know that this guy gets to be chewed out. They singled him out in their response and said he was new. If they stood behind this policy they would have basically diffused the responsibility without mentioning him by specifically. I could be wrong of course, but he cost a bunch of people a bunch of time and effort and unpleasantness so he'll get yelled at.
They singled him out because the original tweet showed the salesperson's full name and picture. He might lose his job because he unintentionally showed everyone how the sausage of monetizing open source is made.
I don't think the (non-)apology even gave that much, just that the training/policies will be "reviewed", which is even weaker:
>>In light of this incident, Canonical will be reviewing its sales training and policies.
