Encrypting your text messages might make you more of a target under a dictatorship:
The recent demonstrations in Egypt, which overthrew the government, relied heavily on cell phones, and especially texting, to coordinate the massive rallies. It was suspected, and later admitted, that the secret police had already set up a monitoring system for text messages...

Just using encryption enables the police to identify who is doing so, and which type of encryption you are using. If only a few people in the country are using a certain type of encryption, you are suddenly a "person of interest" for the secret police. But if there is widespread unrest, and lots of people are encrypting their text messages, the cops are screwed.
