yes, at some point actual human intentions must come into play. you can't defend stuff like CP by saying "it's just some EM pulses, what's the big deal?". or "no I'm not invading your privacy with my IR camera, you are broadcasting in the IR spectrum!".
in this case the implementation does blur the line a little bit. what if the browser's memory gets swapped out to a page file on a (spinning) hard drive? even if the cache gets "deleted" after closing the tab, it might be quite a while before the sectors containing that protected sequence of bits get overwritten. is this infringement?
