> A -> B does not imply !B -> !A

A -> B does imply !B -> !A. The error in reasoning here seems to be that attitude towards a website is assumed to be a binary "like/not like" variable, while in reality one can also neither like nor dislike something.

No it doesn't. Just because you tell me you don't like to get shot doesn't mean you are ok with being stabbed.

[tr352 → snovv_crash]

Yes it does. In fact, in classical logic, A->B is equivalent to !B->!A. See https://en.m.wikipedia.org/wiki/Contraposition

[spookyuser → tr352]

Exactly.

A consequence of this being true is the Raven Paradox [1], seemingly the OP has solved the classic riddle in a HN thread.

While it pains me to admit: They're actually right, and I was wrong above.
