On the other hand, this is a very public issue, and (as of writing) at least 32 people want to know his opinion. So, by community decision, I'd say that this post is appropriate.
Don't you think this is akin to piracy? Why are people so outraged about someone using a simple HTML page (or parts of it) without permission when illegally obtaining and using content such as movies or music is a daily occurrence, but you don't see people making a big fuss about that.
I'm not saying what he did was right as it obviously isn't, but making such an outrage about this seems a little bit over the top, IMO.
I'm going to kill this now though.
