Complaining about analogies is like complaining that the morphism between (Q, +, ✕) and (R, +, ✕) is not a good example because there's no √: Q -> Q. That's simply wrong, it's a very good example. They are both vector spaces and the morphism, the analogy, captures the essence of the similar behaviour in the context required.
The analogy was not between introducing regressions in open source vs. commercial software, it was between introducing this particular regression, in the way that it happened, and the abstract idea of doing something so severe in an arbitrary abstract company -- not software company -- any company; something so serious that it warrants immediate dismissal. Surely anyone can think of something that satisfies the above criteria in whatever field they are working without having to bound the free variables and twist the analogy in a way that it fails just to complain that it does.
