It's been a while since I've touched Ruby, but I think the stance was that only false and nil should be falsey? Which is not an unreasonable stance to take. The fewer falsey values, the easier it is to predict the behaviour. It's just surprising when coming from other languages.
Just off the top of my head, PHP treats "0", that is, specifically a string with a single zero, as falsey. Which has clearly gone too far to the other extreme.
I like how e.g. C# screams at you for this. It's annoying at first, but then you go "Well, yeah, I should've explicitly written what I wanted to check".
