If popular usage of a word drifts and the new usage is widely and unambiguously understood by most speakers in a target linguistic community, it is the folks writing articles in objection who do not understand its meaning.

As far as I can tell, the word "cracker" has close to zero uptake outside of the food industry (and, perhaps, people who produce cracks for software). You're far better off letting the context distinguish between the type of hacker, or mentioning it explicitly if the context does not make it clear, since more people will understand what you're talking about.

>Literally doesn't mean figuratively, they're just using the word incorrectly.

Literally has been used to mean figuratively since at least the 1700s[0], and words mean whatever people decide they mean.
