En una entrevista en http://tinyurl.com/b7vuqf: Pregunta: Another area where Linux is used extensively is in hosted software or "cloud computing" where users don't have access to the source code, is this a good or bad thing? Respuesta de Linus: It is to some degree inevitable as within certain classes of software it's the only model that makes sense. Look at Google Maps. It does not make sense to have it on a device. The whole idea is to have it on the cloud because the information is huge and "out there". If that means the user never sees the source code it's not something you complain about it. I'm happy with Linux being used for that. Projects that are specifically designed for software-as-a-service in the backend, and only the output of the project is what gets distributed, then use the Affero GPL. Linux is not that project. One of the problems I had with GPL version 3 was it was possible to add Affero-like extensions and "licence creep" happened which can make future versions of software licence incompatible with previous versions.
