The commercial license is the basic licensing model and it has the same functionality as a personal or an academic licenses. JetBrains offers discounted personal models to support private individuals. It is only the following exception, which allows you to buy a discounted personal license model: If you have to pay it out of your own pocket, you are not getting reimbursed for buying it and you do not use any company detail (company name, company address, company VAT ID) during the purchasing process.
