I've seen a few pivot from "what they said they were going to do" to "we just took all your money thx".

This is similar to how people raising money on crowdfunding sites decide to change/improve the product after beating their targets. This also results in failure usually because they don't deliver the original product and don't really know what they are doing except trying to spend the money they have raised.

Binance did an ICO last year. They made more money than Deutsche Bank did.

But they're the exception in the scamsphere of Ethereum tokens.
