How is TCF licensed?
All TCF code is licensed under the Eclipse Public License (EPL) v1.0. In addition to that, the plain C agent code is also licensed under the Eclipse Distribution License (EDL) v1.0, which is basically a very permissive BSD License in order to make it easier to redistribute the agent binaries linked into embedded devices such as mobile phones and the like with even less obligations than the EPL. To be clear, the agent is dual-licensed under both EPL and EDL which means that adopters can choose under what license they want to use it.
