I still use it occasionally as a scratchpad for working things out, especially in languages I'm not as familiar with. Figuring out how to use a standard library function, class inheritance behavior, edge cases like null handling. I definitely don't see myself ever needing to pay for their product. I'd guess the play is to get into B2B or EDU as a hiring or education platform.
