I'm sorry but this is just a myth, there has never been a free market, government has always subsidized business and human beings don't behave in any rational way economically. Some part of the market is smart enough to not buy stuff but most people aren't, the smart minority is not enough to punish companies to change their behavior.
Protectionism for the rich and big business by state intervention, radical market interference.

The "asymmetry of information" aka ignorance regarding what counts as a good or bad product is off the charts. Then there is the time and energy (money) a person would lose trying to track/fend off hundreds of different companies predatory practices/shitty products, it is simply physically beyond the resources of any one individual to protect themselves.
Then there are systemic problems at the system level with deaths/births of new generation of kids during some window of some new product and because they have no memory of the past of bad company or have any street smarts with money and they are going to fork over the cash to the big bad company because they are new to the world and can't judge product quality for crap.
We see this all the time in the videogame/media industry. It's probably one of the most brazenly corrupt industries on the planet because they know kids and many are bat shit stupid.

The only way you'd ever get accountability in our society is if it was radically reconfigured so that the adult participants in the market had some say over companies were managed, I read some interesting ideas of the public being a shareholder in all big companies and when big companies try to pull shit against the public interest they get removed. Either way the only way you'd get accountability from a company selling you stuff is if you were physically close enough to the company to force the issue because there are too many others who are ignorant feeding the company the company can survive off of.
Right now we live in a totally nakedly criminal world and most people are unaware how criminal it really is because they don't have time to sit down and process what is going on.
