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?

@shauna Re last, I think the biggest example is imessage lack of RCS. I think there have been emails revealed in court proceedings from Apple to the effect that they see the imessage lock-in as a competative advantage.
Apple says iMessage on Android ‘will hurt us more than help us’

Apple knows that iMessage’s blue bubbles are a big barrier to people switching to Android, which is why the service has never appeared on Google’s mobile operating system. That’s according to a court filing from Epic Games.
