I'm the author of the post, mine was sarcasm.

I wanted to explain two things:

1. A Design pattern or an opinion can be right for some people, wrong for other. There is no such thing as absolute truth.

2. Indirection in software development is a subjective matter. MVC can be fine for some people, not enough or overkilling for other. But argumenting things with "My solution works" or "I use it in my successful business" is nonsense.

That questionable Ruby snippet isn't something that I'd use for real.
