Why do you take this personally? Just use opensubtitles.com instead of their old opensubtitles.org?
They are only changing the old .org API, because they are moving on to their new website and REST API that they've been working on for a while. The new REST API is still free for 5-10 subtitle downloads a day.
Or you can download directly on the website.
I prefer either physical or audiobooks. I seem to have a hard time concentrating and reading books digitally.
