Does the system respect the project's license?

If not, then JetBrains may be liable immediately when anyone opens project they don't have rights to, or which uses a license incompatible with the model training JetBrains wants to do.

They can't expect every bit of code opened in their editor to be "free" for them to train on, even if they probably say so in their EULA, as they can't be sure the person opening the code has the rights to transfer/distribute it to Jetbrains for them to train on.
