The anti-spoiler crowd are pretty demanding. A large and vocal group fought hard to introduce prominent spoiler warnings on Wikipedia. There was a time when every other literary work there had a warning that the article might be discussing the subject at hand.
It's a strange phenomena, and I'm not entirely convinced that it doesn't imply poor quality entertainment. Good quality entertainment is eminently re-watchable. How many times have I seen "Groundhog Day", or read "Lord of the Rings"? The fact that I know exactly what happens doesn't seem to diminish my enjoyment at all. In fact, it seems like with every re-experience I pick up some new detail or insight.
OTOH I can totally understand spoiler alerts with respect to sport and sporting-type events (like politics). It usually does seem to diminish the pleasure of watching a game when you know the outcome.
I don't think that the actual amount was mentioned until the last run of episodes. Prior to that I only remember it being a huge pile of cash that they had "stopped counting."
I don't think that an amount of money constitutes a spoiler, unless that very specific amount has something to do with a specific plot point. ("Ouch, my cancer! If only I had $80,000,001 exactly!")
I always err on the side of "it's a spoiler". If it's not in the show's trailer, I treat it like a spoiler.
I know that I'm personally much more sensitive to spoilers than a lot of other people, so it always annoys me how somebody says something thinking they're not spoiling anything without fully thinking through the implications of what it is they're saying. It's almost arrogance, really, to simply assume that you know what will and will not spoil some given experience for another person.
