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
Plase don't overlook that @signalapp removed SMS/MMS interoperability from their Android app against the vociferous objections of their user community.
@prmam What was their ostensible reason? And why do you think they did it? (If you don't mind my asking; I can always do a web search)
@shauna @prmam IIRC they discovered that despite labels and warnings about SMS in-app, some users assumed that ANY message sent from Signal was encrypted. So they removed all possibility of confusion.
