Thanks for the link. What I take away from it is that Stallman's full opinion on SaaS is internally inconsistent, either that or I am completely misunderstanding him. The "Distinguishing SaaS from Other Network Services" section was exceptionally incoherent; here's one quote:

> Multiplayer games are a group activity carried out on someone else's server, which makes them SaaS. But where the data involved is just the state of play and the score, the worst wrong the operator might commit is favoritism. You might well ignore that risk, since it seems unlikely and very little is at stake. On the other hand, when the game becomes more than just a game, the issue changes.

So, SaaS is okay so long as the "risks" are sufficiently small? Who defines that risk, me? So that makes it okay for me to use Google Docs, since I deem the risk of Google doing something evil with my documents to be small? (Well, no, because Stallman explicitly calls out Docs as unacceptable. So I guess I better not use that.)

Or from the conclusion:

> Don't buy or install “thin clients”, which are simply computers so weak they make you do the real work on a server, unless you're going to use them with your server.

...thus violating the "essential freedoms" of anyone who uses your thin clients?

This is (one of the reasons) why it's so hard to take Stallman and his "four essential freedoms" seriously.
