Yahoo, which is now part of Verizon's larger Oath company, has been struggling to remain relevant in Google's and Apple's world. A Yahoo! email address is now both a source of ridicule as well as concern. The latter comes after Yahoo's admission of privacy breaches and its repeated inability to secure its customers' data. Now it seems to be tempting fate yet again by introducing a new chat platform, simply called Squirrel, that, curiously, doesn't advertise any security features or encryption.
