How does this differ in goals or intent from Singularity?
singularity must be installed by an administrator of the system, binctr doesn't care about having privileged components installed.
binctr is a lot smaller and more grass-roots as well, which could be good or bad.
It's possible singularity wishes to also have truly unprivileged containers, but if that is one of its goals, it currently fails at it.
The Joke starts with a question in the format what is the difference between A & B where one of these A is to be the Butt of the joke. The answer then says one is X where X is a number of qualities, probably laudable, obviously describing A, then the punchline is the description the other is Y with all negative qualities in such a way that you realize that the previous description of X which you thought was referring to A was actually referring to B and the negative Y is a particularly mean spirited description of A. One common variant if you have the negative Y values described first you will just say 'Well one is Y (all negative values) and the other one is A (just repeating the name)'
The comment was written in such a way that it functioned like one of those jokes. I unfortunately cannot think of one of these jokes right now, but for an example of how the reversed version works you might have something like this:
What is the difference between X and Ted Bundy?
Well one is an insane Republican murdering abuser of women, and the other is Ted Bundy.
No particular person was thought of as being represented by X when this example joke was formulated.
You can probably find some examples here https://worstjokesever.com/difference although I wasn't able to - warning the first joke is racist.
What is the difference between USA and USB? One connects to all of your devices and accesses the data, the other is a hardware standard.
