IDK about Tomato, but initially DD-WRT was a customized original firmware for something like Asus 500 router. Then, they switched to OpenWRT codebase with addition of proprietary drivers and customized web-interface. So at the beginning it have some sense, as better, more open version of manufacturer firmware with additional features and with fixed bugs and closed backdoors like unchangeable root password.
