An example of a vulnerability of an even older version of Opera for Windows, that let an attacker totally own the client computer: https://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2010-13...
"Large values in the HTTP Content-Length header can cause Opera to crash. Certain specific values can cause a memory corruption, which in some cases can allow arbitrary code to be injected and executed. In most cases Opera will just crash. To inject code, additional techniques will have to be employed."

And overflows in the image handlers which crop up every now and then. Anyone that thinks they are secure using an outdated and insecure browser by disabling JavaScript doesn't understand security's complexities when dealing with something like a browser.

Someone finds a zero day html parser vulnerability and takes over your computer by putting the malicious markup in a banner ad.
More experienced users are not safer in any way if they're using unpatched and unsupported software.
My dad hates upgrading software because they mess with the UI and remove features he likes. He is not security conscious and is subject to attack.
The vendors take shortcuts, and force UX on usera because they don't want to bother back porting security fixes or making security code separable from UX feature code
What's the actual risk though? I have a feeling these users are also the more experienced and cautious ones, the ones with JS off by default, the ones who aren't going to be as easily tricked by social engineering, and that already removes 99% of the attack area.
