I agree. There are similar laws for many other industries already that either prohibit or put operational restrictions such that their "on the platform" subsidiaries are on equal footing with competition. Enron was breaking this principle when their energy traders would call up a power plant they also owned and ask for an unscheduled outage. I don't remember if this was specifically illegal in this case, but I used to have to take an online class once a year to remind me not to share any non-public data with marketing in one such regulated industry and that there would be serious consequences if this rule was broken.
