It's only because lying ("puffery") about everything has become the norm in corporate America that indeed, almost all listed companies commit securities fraud. If they'd go back to being honest businessmen, no more securities fraud. Just stop claiming things that aren't true. This is a very real option they could take. If they don't, then they're willingly and knowingly commiting securities fraud. But the meme makes it sound to people as if it's unavoidable, when it's anything but.
If Mark, both through Meta and through his own resources, has the capital to hire and retain the best AI researchers / teams, and claims he's doing so, but puts out a model that sucks, he's liable. It's probably not directly fraud, but if he claims he's trying to compete with Google or Microsoft or Apple or whoever, yet doesn't adequately deploy a comparable amount of resources, capital, people, whatever, and doesn't explain why, it could (stretch) be securities fraud....I think.
