No, it’s really not. Poorly protected cells get charged too quickly, discharged too quickly and over-discharged which makes them much more likely to fail in a violent way. I have seen loads of off-brand tool batteries burn up in power tools because they do not have the, expensive, protection circuit that comes with a name brand battery.
Again, this is hysterical handwringing and over exaggeration.
