I'm still really sad over the death of EdgeHTML. It was the best browser engine I've ever used, and I wish they at least open sourced it when they abandoned it so the community could continue maintaining it (and port it to Linux)
Alphabet really needs to get antitrusted. They make one of two fully-featured browser engines, which is the one almost everyone uses, while also being the target of 21% of Internet traffic. So frustrating.
