Are you me? Because this is me.

The iPhone keyboard requires 2 taps for punctuation, including periods. Americans (and iirc especially younger ones) use more iPhones than Android phones (don’t know about other countries, but OP indicated in a comment that they’re in the US). I’m not some old guy saying the youngsters are just lazy, but I do think the iPhone keyboard is a factor in how text-based communication has evolved.

Pleasing the copyright holders. I don’t know how it is for the Dutch national library, but with a system used by many libraries in the US there’s a cost to the library based on the number of times it’s checked out, so more revenue for the copyright holder and the digital middle man. Allowing you to have the e-book indefinitely would be, at least in their minds, no different than giving it away. 🤷
