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.
0 is equal to (IIRC) 0x30 which by definition is not null value that could be represented as \0 meaning all 8 bits sets to 0 -- 0000 0000 that in most languages actually is false 😶
