This is another one of those telling bits.

The hoaxies act only on expectations and outward appearance. To them, the thermal cladding needs to be described as "crude" or similar. Because they only have simple measurements for whether something is appropriate, adequate, and well-executed. So they reach for "how neat is it" and think that is meaningful.

An engineering student will look at the thermal materials and ask "What is going on here? What is the application and constraints?"

And you realize quickly that the material would have to be extremely light, and therefor fragile. And that immediately constrains the fastening methods available.

And if you keep thinking about it, you might even realize that the crinkling isn't an error; it is a FEATURE. First off, to increase surface area (or, more complexly, it creates a wider view angle, removing what might otherwise be local difficulties in radiating heat). It also is crinkled because that reduces the mechanical contact; it makes conduction of heat less efficient.

When you realize what you are looking at is an engineering solution for an alien environment, your eyes are much, much different from eyes that look only for what they might find casually familiar (probably through media exposure, since their actual contact with working spacecraft is minimal).
