You're missing the most important cases - there are cases where it could go both ways in terms of ISA vs. HASA, in which case (the article says) you should use HASA.

Just saying "use the tool appropriate to the job" dismisses the entire problem where in the real world, it isn't clear what that is.

I'm not responding to the article, I'm responding to the parent, who is saying that encapsulation is "much favored" over inheritance. It is not. At least, not amongst more experienced programmers.

Even in marginal cases, you can reasonably decide that a data model should use inheritance. There's no presumptive bias against it.
