Being blocked from access to books is similar to being blocked from information generally (i.e. the Internet, which is where books now exist).
Are bookstores oppressive because they don't have every book? Is wiki because they don't let you edit whatever you want?
Do you not still have access through other means?
Okay, but you’re still missing the relationship between objects and the practice of one’s cognitive liberty facilitated those objects. It’s the oppression of cognitive liberty that is the problem. The objects involved are just working for your doublespeak to conflate and trivialize the oppression of a demographic of people.
And your missing the point of your not entitled to it either. Why does a website HAVE to cater yo how you wish to access? Because the website still has every right to tell you to kick sand. A bookstore can ban you for wearing a backpack. This is the society we live in.
You accessing content still consumes resources, why should the server owner pay for your access your way?
