I think it makes sense to note that corporations don't adhere to GAAP voluntarily, or because it makes good business sense. They do it because they will be de-listed from stock exchanges and shut down by the government if they do not.
The stock exchanges won't do this for "tech malpractice." From a financial standpoint, tech malpractice is just another calculated risk. Versus financial malpractice, which creates an unlevel playing field on the stock exchange itself. And history has shown that the fallout from "tech malpractice" ends up costing comparatively low dollar amounts anyway.
This leaves me at: this won't improve without government regulation.
