The article doesn't state they target uneducated people, it states that they use it more which are subtle but key differences. Furthermore "poor people who don’t understand credit" is not the same category as "lower incomes, lower education, and worse credit (redundancies here)". Even if we assume they are the same group of people (by making an equivalence between understanding of credit and general education/income/credit which we know is not a great assumption) the statements are different anyway.
The article is talking about an observed statistic, BNPL seems to be more prevalent in lower income, lower education and worse credit populations (we actually have really poor data on private credit so this should be taken with a grain of salt). The commenter however is making the claim that this is because they have a bad understanding of credit, and also implicitily that BNPL is bad and a bad use of credit.
These are therefore different as we can easily see for instance that a probable cause could for example be that people with no savings are more likely to borrow to cover spending in-between paychecks for example, or when emergency expenses change their cash-flow. This would not however fit with the commenters viewpoint, and is actually a good use of credit.
If you could declare bankruptcy (Hey. I just wanted you to know that you can't just say the word "bankruptcy" and expect anything to happen.) the moment your credit card bill arrived, no bank would extend you credit beyond what you specifically had on deposit with them to secure it (just like home mortgages are secured by the home).
The thing is, a lot of poor people live like that every day. I have some friends who are a single car problem away from being financially destitute because of the death spiral that can come from being poor- your car that you drive to work breaks down and you don't have the money to fix it. You lose your job because you can't get to work, and you can't get another job because you don't have transportation. Public transit is non existent in most of the US. You can get another car, but it's a junker at an insane interest rate and that's another expense you don't need. So yeah in that headspace I can understand feeling like financing a burrito could make sense. If you're already not thinking straight and you're tempted by a simple pleasure that feels like the one thing you can control in life and you know you're going to have the bank balance tomorrow, I can see it.
People wanting stuff like this doesn't mean it's rational to use or moral to offer. It's a symptom of a society that is fundamentally broken, that is designed to keep people on the razor's edge of their current economic status and in constant fear of losing what little they have.
*If you're curious how this happens, I take an expensive medication for a chronic illness and my insurance randomly changed how they pay for it without informing me before I got hit with a $2000 bill
OTOH, the article literally says that "data [shows] that those with lower incomes, lower education, and worse credit (redundancies here) are more likely to use BNPL."
Most consumer protection laws are somewhat patronizing, but since you can't be an expert in everything, we need them.
