why do you think that someone need a clone of Chrome?
We don't think, we know. The old rendering engine was falling behind technologically and the dev team felt their resources would be better utilized by adopting a renderer made by someone else and focusing on building a good UI for it instead of trying to compete with companies like Google and Microsoft. The old Opera UI was not compatible with the new renderer and it would have taken more work to adapt it then start from scratch. So, here we are.
