> The simple solution for this problem is that Apple should actually provide all of the security updates for all of the operating systems that it is actively updating

That's circular reasoning. The older operating systems are only getting security updates, as the article notes, so their definition of "actively updating" is "getting security updates". When Apple isn't issuing security updates, it is not "actively updating".

Maybe what the author wants to say is something along the lines that Apple should provide timely security updates for all operating systems released over the past 10-15 years.
