Twitter has updated its developer rules to ban third-party clients, almost a week after it unceremoniously blocked the apps’ access to its platform, offering almost no explanation to what was going on (via Engadget). The new rules state that you can’t use Twitter’s API or content to “create or attempt to create a substitute or similar service or product to the Twitter Applications.”

The rules, updated on Thursday, make it clear what that means: “Twitter Applications” refers to the company’s “consumer facing products, services, applications, websites, web pages, platforms, and other offerings, including without limitation, those offered via https://twitter.com and Twitter’s mobile applications.” The clause banning alternative services was added to the rules with the most recent update, according to the Wayback Machine.

There seemingly hasn’t been any official announcement of the rule change, either from Twitter Dev or Elon Musk. Twitter doesn’t have a communications department to contact.
