Isolating a single word out of context isn't something I would equate with a good faith comment. The comment author sounds like an unhinged lunatic driven to irrelevant knee jerk reactions.
The author, in the context of an article talking about how big companies can bypass various monopoly and privacy laws, wrote how: "companies really do get away with both literal and figurative murder".
That's a general statement about what companies can get away with. He didn't assign cookie violations to "literal murder". It's obvious that "figurative murder" is the kind he abscribes to the violations he talks about, like GDPR.
As in the very common figurative idiom "getting away with murder", which is about doing bad stuff/breaking the law, and not having any serious consequence. Or do you pretend to never have heard of it?
As for the general statement, it still stands. Companies have historically also gotten away with literal murder too, and it's a valid point to raise when talking about how companies can often violate laws with impunity.
