The idea of "stealing a meme" is clearly absurd — you aren't depriving anyone of anything to serve your own interest. Memes are cultural objects used to promote collective and righteous causes. It highlights the ridiculous nature of copyright as currently framed: making ideas into physical objects, and presuming the spread of ideas can be turned into property. We still need to reward creators and their innate rights (like to be recognised as author). Just the way we have been going about it leads to Disney and lawyers everywhere, and it's not worked out well for society.
