I'm looking for examples of UX/interface design where:

* users started using a feature in a way that wasn't intended (can be for good or for ill)
* the product team responded by removing the feature entirely

Also very interested in interfaces where there is an obvious feature that users would want/need that's not provided, and that feature is obviously not provided because it's against the interests of the company who makes the software.

Can anyone think of examples which fit?
