People criticize for making tons of small classes instead of fewer larger classes.How is well-organized code more difficult to understand?

This isn't really a question. Writing a few "large" omnibus classes is simply bad design.
There are several variations on the theme …

Sigh.
There are three distinct things here.
Emphasis on the "More On" as in "Moron". This is a standard design error story. The issue is that inheritance happens along an "axis" or "dimension" where the subclasses are at different points along that axis. Multi-dimensional inheritance is an EPIC FAIL.

Objects are everywhere.
Weirdly, some people can't see them. I guess they live in a rarified, HP Lovecraftian world of pure action inhabited by amorphous things that can't be properly called "beings" but rather "doings" because they're pure activity with no existence.
Read "Hypnos". "They were sensations, yet within them …

Consider some of the common design patterns.
Strategy. Confronted with alternative strategy choices, a purely procedural code solution is either
Read this first: "There is something I find interesting about online discussions around performance issues..." It's about Stack Overflow, specifically. Apparently, someone didn't get their question answered and decided it was better to gripe than to rewrite the question.
Let's look at their response in pieces.

These all seem to come from the "Averted Glance" school of management. The best part about the "I don't want to know the details" management is that we need to substitute metrics for understanding. One …

They bother me because they imply that some Brother or Sister Architect has let slip the presence of the Secret Technologies that we Architects are hiding from the Hoi Polloi developers.
These are the real questions …

Also, to make it easier to follow, I made use of the Sphinx "ifconfig" feature to separate the text into two parallel editions: a Python edition …
