I understand Stallman's dislike of SaaSS in [2], but I fail to see how it meets any definition of rent-seeking. People who provide SaaSS are using economies of scale to offer services that are desirable to some, because they're offered at a cost that is less than the cost of developing and maintaining their own private solution. There is certainly a loss of freedom in using these services, as Stallman points out. But rent-seeking, not so much. Users of SaaSS need to decide whether the cost savings of using SaaSS is outweighed by the freedom they give up. Nothing more, so far as I can tell.
