Just because you send me malware after some text I wanted to read (in http response), don't give you rights to force me to execute the malware.
Just because I have your book (or page) and look at part of it doesn't give you the right to force me to read it in full or dictate how I'm reading it.
I have every right to reveal/read only part of the book/page. We didn't sign any agreement, if you want me to first look at the part you want to or agree to some license nothing stopping you to do, stuff like paywall or subscription exists...
