Carbon Dated and Proud
It would be easy to ignore were it not for the treatment of aliens as fully canon ever since (wikis for instance don't treat the aliens like easter eggs like they used to) and FO3 GOTY edition downloads Zeta in by default so not downloading it is no longer an option.
Personally, I couldn't care less about Zeta but I do see the issues of Zeta on the franchise as a whole and the potential issues of its inclusion in canon even if it is ignored (Bethesda'll probably resort to the aliens if it runs out of ideas).
Like I said, is canon really that important? It's all made up licensing anyway.
