To me, ie what follows is only my opinion, the question is why anyone would think anything should be done about it.
It is a very rare thing for soap to actually harm anyone with any lasting damage at all, this includes lye heavy soaps. Remember soap was made hundreds of years ago, when it was much more common for soap to have been lye heavy, yet there are very few stories in which grandma's lye soap did actual harm. Yes no one liked it, and it was said to "take the hide off you" which I assume meant it striped the skin pretty good and maybe even caused a slight chemical burn. That was then- now it is even more rare. . .
Are we worried that new soap makers will do actual harm? I don't think so. I think people get up in arms because they spent the time learning and are a bit miffed that some don't bother. You can't let people who don't spend the time to learn properly bother you. They won't last long you know, they will not harm your business - unless you have a very frail business on the verge of collapse. The people they sell soap to are not all going to abandon the idea of using handcrafted soap either. Some might but most people are a little smarter and have a bit more resilience than that. It is a part of economics that a market expands ( lots of new business ) and then contracts ( only the strongest survive ). What happens in the middle is that fair prices are established that allow the best balance between what is a good buy and what is a good profit.
Don't let it bother you at all. They will come and go - and perhaps a small percentage will actually learn along the way and survive.
