As an astronomer, meteorologist and software engineer for the last 30 years, I have only one thing to say:
You are absolutely correct!
There is no such thing as an "Ozone Hole", only an "Ozone Donut", since the angle of incidence is the single most important aspect.
As you correctly stated, Ozone (O3) is created by sunlight which ionizes oxygen (O2). During the polar winters where there is no sunlight for 6 months out of the year, Ozone is no longer being created.
However, at latitudes above the polar circle, the long duration sunsets produced large quantities of Ozone. That is a simple function of solar incidence (angle between the Sun and the horizon).

Apparently we are in error, according the Cambridge University. To paraphrase Malcome Forbes: "Socialist Tool."
I shiver now in my boots.
Cambridge University was last well respected when I believe Sir Issac Newton was in charge. Don't forget to celebrate his birthday next December 25.
