Exclusivity

Scope is everything in these clauses. A tight one names 3 competing brands and runs 30 days from publish. A loose one bars a whole category, VPNs or meal kits or mobile games, for 6 months with no geographic limit, which can quietly cost more than the deal pays if that category is where your other sponsors come from. All of it is negotiable: the list, the length, the definition of the category, and whether the clock starts at publish or at signature. Price it rather than refusing it. A sponsor asking you to turn work away for half a year should be paying for half a year.
