We are so eager to try and find a neat place for all our interactions. It never works like that. Pretty much everything ends up being relative.
Anywho, as far as definitions go "energetic teamwork" to me does not really qualify, because hustling in any commonly used sense is not at all required to be a team effort.
The point of hustle in the “kids sports team” context is that a team that “hustles” can beat an equally skilled team that doesn’t. In my experience this is also true of other kinds of teams and even in contests among individuals.
"Hustle" was one of my favorite words growing up, because it described something I admired and wanted to embody myself, but I have retired it from my active vocabulary outside of sports contexts, because if it's misunderstood, it's going to be misunderstood as something that I loathe.
A sign-up wizard that splits up users' PII entry so they are invested in the process by the time it asks them for the valuable stuff is a good UX tech example.
Spam messages that pretend to be bills or from an authority are well into dishonest territory. The key difference seems to be in the honesty of the problematization. It's a continuum.
The best hustles play on the target's conceits, the worst on their virtues. 3-card monte plays on greed and a sense of superiority.
Business ones are basically blackmail like, "everyone thinks you're a smart problem solver who is easy to work with, if you want that to continue to be true, you will solve this problem for me, I'll let you know when you're finished." Less tech oriented, but the leverage pattern is similar.
Yeah there's the meaning in sports which was probably the first I ever encountered, but it's pretty different from the startup/business definition (one might relate them, but they seem to me to carry pretty different connotations) and again, in the context of some kind of money-making venture my association with it was 100% "scamming folks".
