“…Digital products are largely experience goods, where it can be difficult for the consumer to gauge the true value of the products before using them (Caves, 2003; Shapiro et al, 1998). One reason for offering a freemium strategy is that the free version can allow customers to try the product, while expecting that a considerable segment will purchase the premium version for a higher fee, once they truly understand the product's value (Chellappa & Shivendu, 2005; Datta, Foubert, & Van Heerde, 2015; Dey, Lahiri, & Liu, 2013; Greenstein & Markovich, 2012; Lee & Tan, 2013; Nan, Wu, Li, & Tan, 2018). This phenomenon is related to the literature on word‐of‐mouth diffusion (Dou, Niculescu, & Wu, 2013; Godes & Mayzlin, 2009; Kretschmer & Peukert, 2020; Niculescu & Wu, 2014).…”
