Trisquel is not SaaSS and neither is Facebook (for the most part): SaaSS is
doing your own computing on someone else server when you could do it on your
own computer. For instance using an online translator instead of installing
one on your system.
When posting something on a website, you are communicating. Sure, you could
have your own server but why would the reader have to use your server (to
answer for example)? Communicating is not doing your own computing. It is a
shared activity and none of the party deserves the control of it more than
the other.
That said, do not use Facebook! Not because it is SaaSS but because huge
centralized database about everybody (even nonusers!) is a huge threat to our
privacies.
