Exploit is a really, really strong word. The way oracle refuses to acknowledge any software processor boundaries other than their own is more exploitative.

It's been several years, but if I remember correctly if you wanted to run an Oracle DB on a 2vcpu VM you couldn't just license 2 cores, you had to license every core on every hypervisor the VM could run on.

It basically means you have to get off oracle or buy oracle hardware. For large enterprises with old hardware running decades worth of business logic captured in stored procedures it's becomes a rock and a hard place situation.
