Most programmers have never made a LORA and have never used Stable Diffusion. For 99.9% of people outside the programmer class, this is absolutely an "advanced algorithm."
Just because you understand what it's doing under the hood, and just because it can be abstracted into a handful of discrete steps, doesn't mean it isn't advanced.
GP isn't saying "this product would never work" (which is reminiscent of the classic Dropbox comment), GP is saying "this isn't 'advanced' and you can do it yourself" which is really helpful and exactly the sort of thing I love to see on HN.
Where do you think we are?
>this is absolutely an "advanced algorithm."
When someone puts that on his product's page, it's assumed that he developed said algorithm, or at least had a hand in it. Instead, here the real product is the pipeline and not the "algorithm". The product would do better if it was honest about what it did.
And like I mentioned, Dreambooth is pretty "old" now. The service could probably be much cheaper if the OP moved to using LORAs, and it would give better results, because it wouldn't clash with the tokens in the underlying model, and could be used with any model.

Though, I agree with you that the real product here is the pipeline. The parent comment is also correct though in that the majority of people aren't in a place where they can train their own models yet despite it being possible for them. This product is taking advantage of the current arbitrage opportunity.
