Not sure about that number - they give no details on how it's calculated and anyways it's presented as being sales, not profits. Edit: https://www.marketplace.org/2019/11/18/how-amazons-counterfe... has more details and is where OP ironically appears to be ripping off from. Says 1.5 million is 4% of sales, so they did around 37 million in sales.
Based on what? Why would your gut reaction to this entire story be "I'm suspicious of that dollar amount" [1]?. The fact that it's revenue and not sales doesn't somehow make the headline false. It's still a loss of revenue.
The broader point of this story and others is that Amazon has a rampant counterfeit goods problem and they do little to nothing to ensure authenticity for consumers.

It's a local news station. Watch the video. They interviewed the manufacturer. They likely read the original story and decided to bring additional attention to a local business.
