February: Twitter delays charging for API after user backlash
Reddit faced a major dose of user retaliation this year when the company announced that it would be charging for access to its application programming interface, also known as an API. Twitter nearly did the same earlier in the year, and promptly dodged a bullet, only to shoot itself in the foot a few months later. In February, Twitter announced that it would be charging for access to its API only to reverse course after users expressed their discontent.
