In theory there are no rules about importing code, beyond the usual licensing issues. But people use SO and such all of the time, right? If one *really* wanted to do a global audit of improperly imported code, we'd all have bigger problems. So from that perspective it's status quo. But I don't want to be the person caught uploading proprietary code to another company's servers. It's not a major issue, and I doubt it'd ever be a practical problem. But fear of punishment keeps me away.
