The edit tweet button isn’t Twitter’s only new feature that can rewrite history. The company has apparently changed the way it handles embedded tweets that were deleted after the fact, littering webpages across the internet with holes.

Previously, a deleted tweet embedded in a webpage would still display the text content of a tweet. Now that text is gone, showing only a blank box. Twitter is altering webpages with deleted embedded tweets by hiding the text with Javascript — a choice that has many developers and open web advocates up in arms.
