Not a Tesla fan but this article is garbage. Basically all sheet metal comes on coils "that resemble toilet paper" including the metal that other manufacturers use.
It definitely seems like an irrelevant point. All car sheet steel arrives in rolls.
I'd be more concerned about how it is formed into panels, how resistant it is to corrosion, what tolerances parts have, how easy is it to replace parts, whether there are visible production flaws due to it being naked steel, and if construction techniques or material thickness makes it more dangerous to occupants or pedestrians in collisions.
I certainly won't be surprised if pictures start appearing in a year or two of cybertrucks that have been completely fucked by salt water corrosion, or heat warppage or other issues caused by their design.
The missing point is it's a property of stainless steel that it remembers being a coil and can unflatten itself weeks later if the manufacturer doesn't know how to work around that.
I've worked with stainless steel (specifically 304, 430 and 401) for 15 years and the steel shouldn't have a memory after being run through a de-coiling machine that is configured properly. Excessive heat in a focused area would definitely cause it to warp but this can usually be overcome by adding geometry to stiffen the parts. It seems like the team at Tesla is missing a step somewhere.
