The Register: Verizon!-owned! Yahoo! bins! AT&T! IDs! for! Tumblr! logins! (nothing weird is happening with the headline; when it comes to Yahoo, The Register believes in exclamation points.) “Verizon has moved to unwind an old deal between Yahoo! and AT&T that allowed users to run merged AT&T and Yahoo! e-mail accounts for login to some Yahoo! services. Tumblr was acquired by Yahoo! in 2013 and became a familiar Purple Palace bungle: after splashing US$1.1 billion to buy the blogging platform, it January this year wrote off $482 million of its value in 2016.”
