Like the competitiveness of open models versus Op*nAI and the like. I don't see a reason to pay myself. The few times I've asked something to spit out the husk of a program in a language I'll never learn or use again, the commercial options were just as competent as the open one that ran locally.

Image generators are pretty much on par whether proprietary or open from what I can tell. Haven't really messed with voice or anything else myself.
