For a whole bunch of people who use your service, developers who have built products that support your service, you gave them a week's notice. This is just straight terrible leadership, @dougblackjr/Twitter.<br />Next week, there won't be a free Twitter API anymore. As a result, I will stop any work on non-commercial projects that use the API and will have to re-evaluate which commercial projects are still feasible, @luca/Twitter.<br />This change will destroy research, activism and commercial projects, @luca/Twitter
