This is exactly the reason UL exists. The specific purpose of their standards -testing for public safety- is served by their testing products for these hazards.
If the products you describe are UL listed, the folks at UL would be very interested in any documentation / examples you might have.
If the products are not UL listed.. well, you save a buck or two. Your choice, your risk.
If the UL label is a fraud, again, UL would love to see it.
Finally, never underestimate the power of the marketplace. I can think of a few automobiles that met every standard, yet are history - because they were flawed. Some were even made by huge firms that "owned" the market. Sure they did.
Finally, have you written the companies involved? Some of them actually do seem to be in the business of selling quality products.
A call for governmental involvement should be the last recourse ... not the first. It has been said that, ultimately, government is expected to do three things: deliver the mail, pave the roads, and secure the borders .... once they do those jobs, THEN maybe we can trust them with another.
