Although I agree that "scam" is extreme, the commercial side was sullied in the early 2010s by D-Wave selling what they described as "quantum computers" for $10m and spinning up a bunch of misleading PR. Of course you expect a certain deree of "fake it til you make it" in such companies, but they'd been going for over a decade at that point. This was all kicking off as I was doing my PhD in the field. It was eye-opening to see how little attention was paid to serious academics vs hucksters, and how companies like Google could be duped into spending millions on basically nothing.
