Don't forget freedom 0: the freedom to run the software. This is actually the
most fundamental freedom granted by Free softwares. Indeed, the other freedom
are irrelevant without freedom 0: if you don't run your own copy of the
software, you just do not know what code is executed even if this software is
distributed under a Free software license! Indeed, by using a, so-called,
service on the Internet you were not distributed the software beforehand. It
is not your copy and the owner of the service may modify the service as she
wishes. If this service is a Free software, this is even guaranteed by
freedom 1!
To fight against this threat (SaaS), every user should understand the danger
of letting her computing in the hand (well, in the CPU) of other people. For
instance they should prefer LibreOffice (or any other Free software word
processor) and refuse Google Docs. However, as I wrote in my last post,
crawling the Web is not your computing. That is why it should not be regarded
as SaaS.
That is RMS's vision too:

argument will certainly make you more thoroughly consider my point ;-) )
