Edge. Couple of years ago I was really pissed how they fucked up the merge between Hotmail and Skype, I lost so many "friends" because they killed MSN / hotmail.
Microsoft first licensed Internet Explorer in 1994. It's most used engine Trident was released in 1997. IE/Edge was discontinued in 2019. That's one hell of an "Embrace Extend Extingush" cycle.
