Well, this post is the one that I find myself agreeing the most with you on. Primarily, because the issue discussed here is inherently subjective, the math is objective, and that every business is - at the end of the day - a business. The Butterbeer treats are a bit pricey, so I suppose that they cash-grabbed-me every time I purchase one. The only thing is, the context in which the terms and issues are being discussed, "cash grab" came off as a bit more derogatory than just for-profit business; suggesting that the benefit derived may not worth the money spent (subjective).
As I've discussed here before, I find that the benefits of a hopper ticket are much more vast than the ability to experience HE as an attraction (albeit a hybrid one), which is why I wouldn't really call it a "cash grab." I've never purchased WDW/OUR tickets/passes that are not hoppers, because I like to hop, even though WDW doesn't have an "upcharge attraction" equivalent. But if we're going to define "cash grab" as anything for which a customer exchanges money for goods or services, then sure, everything is a cash grab. I was already "grabbed" a few times today, and it had nothing to do with any theme parks.
