No, they won't, because of many reasons - it's a well-known market failure mode.

Importantly, to pick just one of the reasons, you can't expect users to accurately judge complex technological product, especially when facing marketers who will lie to them. When you're shopping for food or medicine, you're not expected to understand biochemistry or technicalities of randomized control trials - you expect the things you buy to not poison you. Plenty of vendors would be happy to sell you literal poison - and they did, in the past - but we've regulated that possibility away. Similarly, for technology, some of the abuses need to be regulated away, because you can't expect regular people to avoid the traps, and the vendors to not be abusive without external pressure.
