The messiness of the real-world unfortunately doesn't play well with ambiguity in licences :)
It'll be a headache for every large company which now has to send the licence to their legal teams who have to ask these kind of questions (another interesting one is "can contractors touch our terraform setup?") - in fairness to Hashicorp they've tried to address some of these issues in their FAQ, but the FAQ isn't legally binding so legal teams have to go on what's actually written in the licence.
