Fiscal prudence?
If one is that concerned about someone exploiting an OS level security flaw to exfiltrate their online banking credentials (wildly unlikely), they should just be doing that stuff in a VM or similarly isolated environment anyways.
For a while, yes, but the browser being up-to-date doesn't make an EOL OS safe to expose to the Internet.

Just doing sensitive stuff in a VM isn't good protection at all, since a malicious host can trivially compromise the guest.
It can, Ubuntu runs just fine on it
