With E-Readers, there is also the problem of ownership, as more and more companies are deleting content from digital libraries, due to intellectual properties. laws and other reasons, which means knowledge, art and the vision of the author will continue to be lost.
This dynamic can be comparable to the state of most media (movie and game) digital libraries, and streaming, with niche titles disappearing often, requiring they take on predatory tactics to squeeze the user in order to remain competitive and relevant in the market place algorithms (If not popular, the title in most cases are buried, unless they pay the platform to push notoriety to the content.).
This to me is a absolute shame!
Once you own a real physical book, if you look after it and care for it, then no one can take it from you.
