I think the issue is people are using tools in an automated fashion and running up a compute bill for free when they were only meant to be used by humans in a more limited capacity (for companies to gather data on how to improve their products for humans). I think the correct way to use these models in an automated fashion is via the APIs and even then they might also worry about things like abuse/distillation type attacks still if the volume is too high. I think the lack of transparency might actually be by design so that people abusing their services don't figure out what triggers them losing their accounts. I could be wrong of course, this is just speculation on my part.
