I think it's a valuable news function to highlight that some of these coaches may be somewhere from misleading to fraudulent. That said, I think there's an paternalism to a lot of articles of this variety, where implicitly messages of type "thing X is bad" and "thing X should be regulated/illegal" are mixed together.
The nature of being adults with money and agency is that people will be trying to sell you things, and you will largely be permitted to give them money for their product. If you don't like the product, don't buy it. It's one thing if we're regulating something like food or drugs, where the average consumer can't possibly verify if e.g. an ingredient list is misleading, but here you're just straightforwardly getting some advice/coaching -- kinda up to you to decide whether it's worth it.
