This problem involved the business model and policy regulation of the e-book platform. E-book platforms often provide special offers and benefits to students and instructors to attract them to use the platform and buy e-books. These offers and benefits usually include free downloads of certain e-books, discounted prices, and other special features. This was because the business model of e-book platforms usually achieved profit by charging the end user a fee. Students and education workers were important customers of the platform, and providing them with special offers and benefits would help increase the user base and income of the platform. In addition, the government usually regulated e-book platforms to ensure that the content on the platform was legal, healthy, and safe. Special offers and benefits for students and education workers could be seen as an incentive for students to legally read e-books in line with government regulations. Therefore, e-book platforms usually only offered special benefits and benefits to students for the sake of business models and policy regulation.
