That is to miss the point. Nobody give a shit how much money can be made selling Debian. The users care about how much they can get done by using Debian. Software has essentially zero replication cost, so those who try to make a lot of money from it are rent seekers. The challenge then is how to create software in the fist place. Those that charge for software and provide continued high quality development will be OK, while those that buy RedHat just to make money will not (long term).
