One thing I've learned from reading HN over the years: Few things kill the buzz of a new site like the introduction of legal/copyright issues.

I don't see the big deal; it's cosmetic. The logo's easy to remove. I can't imagine significant damages. Legal issues are only a problem when the content is infringing, such as video uploads.

I agree, it shouldn't overshadow other stuff. But that's the odd thing about those kinds of issues -- they tend to overshadow the work anyway.
