I thought "loss leaders" were specific products sold below cost so customers would buy accessories or subscriptions that have nice profit margins. Like selling cheap printers but expensive ink.
The technical term for "loss leader" usually refers to a place like a grocery store selling some necessity like milk at or below cost, because they know if you compare milk prices and decide to buy there, you'll get other things once you're in the store.
That's different from "sell a dollar for fifty cents until all competitors are dead".
There's also loss leader applied to things like consoles, where they lose money (at first) but make it back on the games.
