The new Opera, i.e. every Opera after Version 15, is a Chromium fork.
That means it carries with it all the small and large behaviors like: Auto-updating. It also has literally no upside over using Opera v12, which still works fine for most things nowadays; and mostly no upsides over using just Chrome, or any other flavor of Chromium.
As such, getting rid of it after this acquisition gives only upside for the safety-conscious user.
I trust the security acumen of the 'many eyes' who work on that project much more than Opera or Firefox. And Google doesn't vacuum up any data unless you volunteer it in Chrome. That's been proven.
