Twitter quietly reversed a controversial decision the company implemented last week, restoring the text of since-deleted tweets embedded on external websites. The change was first spotted by Twitter user @RuinDig.

IndieWeb developer Kevin Marks initially called attention to the change in a blog post, criticizing Twitter for “tampering with the public record” by intentionally hiding the text of embedded deleted tweets with JavaScript. Previously, deleted embedded tweets would still display their text content and that behavior is now restored.
