Not to be flippant, but we know that the answer to that is "No" because of Betteridge's Law of Headlines[1]. I haven't read the article ("too hard, didn't care"), but as a foodie: - in certain food circles, it never went away - industrially, McD's in at least North America used beef tallow as one of the par-frying oils for their fries well into the 21st century -- which caused a stir amongst vegetarians and Hindu who…
If you are deep frying, for e.g. french fries, any cooking oil that is solid at room temperature can keep them from being greasy. This includes beef tallow, but also coconut oil for a vegetable-based oil. For some foods the being-solid-at-room-temperature property can be important for texture.
But the premise of the original article (that beef tallow ever went away, which is required for a comeback) is deeply flawed, and the fascionable junk science from RFK is the dumbest possible reason to use beef tallow.
Just don't expect me (a vegetarian) to eat anything that has beef tallow, and expect me to be very pissed off if I later learn a restaurant or food manufacturer uses beef tallow without disclosing it, because that's taking choice away from me.
