noted an RMS interview where he says "'Software as a service' means that you think of a particular server as doing your computing for you. If that's what the server does, you must not use it! If you do your computing on someone else's server, you hand over control of your computing to whoever controls the server. It is like running binary-only software, only worse: it's even harder for you to patch the program that's running on someone else's server than it is to patch a binary copy of a program running on your own computer. Just like non-free software, 'software as a service' is incompatible with your freedom."
