Not legimate, but solar panel tech has made a market for this nonsense.

What’s the legitimate use case for these and female-to-female cables?

Connecting a generator to a house.
The legal way to do it is to install a new breaker, a sliding metal plate that only allows the new breaker to be flipped on when the main breaker is flipped off, and a male wall socket. But that’s expensive and requires permits.
The cheap and easy way is to flip the main breaker off, stick a male-male cord into an existing wall socket, then stick the other end into the generator. But that’s illegal, and could be dangerous if you forget to flip the main breaker off, or plug into the generator before the wall.

None for the male to male especially, because there is no way to involve it in a hot system that doesn’t involve having an exposed prong carrying the receptacles voltage. The female to female is still dangerous, but doesn’t inherently expose the circuit to whatever is in the environment.

Some people claim to use them to plug generators into their homes when the lights go out.
But your generator should plug into some place before the main panel, and it’s easy to put the right connector on that one place destined to it and where you shouldn’t plug anything else. So it’s people not prepared to use a generator, that want to use one anyway, and that have to be sure to disconnect it before the power comes back on or they will find the main use-case for the cable (AKA, the one on the meme).

You should put a transfer switch in so you’re not back feeding power into the grid and shocking some poor guy who isn’t expecting it to be live.

I know if I were to setup the V2L feature on my car to power my home it would look like this (the manual way). But there would be a physical interlock that prevents mains power from being on while this is plugged in.

Legitimate? Basically none. Illegitimate? First, lazily fixing a fuckup on putting up strings of Christmas lights where you can’t daisy chain them properly, with bonus points for the likeliehood of needing to break off the grounding pin. Second, injecting power from a generator into a single circuit of your house if the power is out.
In one sense, you could argue conductors are conductors and if you think through every eventuality you can mitigate risk, but on the other, if you find you’re in a situation where one of these seems useful, you are not the type of person thinks through every eventuality.
