Perhaps Zuckerberg needs no protecting when it comes to these things

Thanks, Dan! But regardless of one's feelings toward Facebook, I think Mark Zuckerberg should be treated with respect here just like anyone else. Not only is it good for the overall tone of the site, but there are enough "public figures" in tech that use this site that a flat "no personal attacks" (without exceptions for fame) seems like the best policy.

I agree completely. But even for people who don't feel that way, there are good reasons for HN to have this rule. Breaking it degrades the community and oneself.
