"A person claiming to be a former Edge developer has today described one such action. For no obvious reason, Google changed YouTube to add a hidden, empty HTML element that overlaid each video. This element disabled Edge's fastest, most efficient hardware accelerated video decoding. It hurt Edge's battery-life performance and took it below Chrome's. The change didn't improve Chrome's performance and didn't appear to serve any real purpose; it just hurt Edge, allowing Google to claim that Chrome's battery life was actually superior to Edge's. Microsoft asked Google if the company could remove the element, to no avail."
