of e-readers brought substantial changes to the publishing industry, also awakening fears and predictions about the possible disappearance of books and print periodicals. Criticism The graphical design of ebooks underlies the format and technical limits of e-readers because most E-ink readers do not support color displays and they have a limited resolution and size. The reading experience (readability) on E-ink displays (that are not back-illuminated) depends on the lighting condition. E-readers are usually designed to only offer access to the online shop of one provider. This structure is referred to as (digital) ecosystem and helps smaller companies (e.g. Kibano Digireader) to compete against multinational companies (like Amazon, Apple, etc.). On the other hand, customers only have the possibility of purchasing books from a limited selection of ebooks in the online shop (accessible via the e-reader) and therefore do not have the possibility of purchasing e-books from the open market. Because of the use of ecosystems, companies are not forced to compete against each other and therefore the cost of e-books do not decrease. With only the option of using an online shop, the social interaction of buying or borrowing a book disappears. In the EU, media products, including paper books, often have a tax reduction. Therefore, the VAT for conventional books was often lower than that of e-books. In legal terms, e-books were considered a service since it was regarded as a temporary lease of the product. Therefore, ebook prices were often similar to paper book prices, even if the production of ebooks has a lower cost. In October 2018, the EU allowed its member countries to charge the same VAT for ebooks as for paper books. Richard Stallman has expressed concern about the perceived loss of freedom or privacy that comes with e-readers, namely the inability to read whatever a reader prefers without the possibility of being tracked. Positive aspects E-readers can hold thousands of books limited only by their memory and use the same physical space as a conventional book. Most E-ink displays are not back-illuminated and therefore seem to cause no more eye strain than a traditional book and less eye strain than LCD screens, with a longer battery life. Features such as the ability to adjust font size and spacing can help people who have difficulty reading or dyslexia. Some e-readers link to definitions or translations of key words.
