Vendor lock-in (also called vendor lockin, consumer lock-in or just lock-in) is
|“||a situation in which the customer depends on a single supplier for a product and cannot easily move to another vendor without sustaining substantial cost or inconvenience. Vendor lock-in can potentially raise costs and stifle innovation and it can result in reduced competition on future related software acquisitions.||”|
"Vendor lockin is a high risk for an SME, and the associated costs (switching costs, or high bills) can be high. At the same time, a vendor lockin does not have a direct impact on the health, safety, security, or economic well-being of citizens."
"Users who buy e-books are often locking the purchase into a platform or hardware system and this could lead to interoperability issues across platforms and problems with consumer lock-in. The choice of reading device will, to varying degrees, affect the range of e-books available to the reader. The degree of vertical integration which has developed across the supply chain for e-books has created commercial incentives to tie the customer's long term investment in the reading hardware to the content of a particular e-book seller."
