I don't understand Wikipedia's article Comparison of machine translation applications. Under "license" a lot of them just says SaaS. But Software as a service is not a license, it's a business modell or mode of distribution, right? It could be free with the AGPL license, for example, or proprietary. Both can be SaaS, that doesn't tell you anything about their license?
What am I missing here?
