It is common for SaaSS dis-services to charge a monthly fee for use. Usually one SaaSS site does not substitute for another, so if users become unhappy with one dis-service provider it is no easy matter to switch to another. When users become dependent on one, it can gouge them at will with repeated small price increases that over time add up to a lot. We view the loss of freedom inherent in SaaSS as worse than the cost in money, but when a dis-service has you over a barrel, the cost can be painful. Thus, even users who don’t see deeper than the bottom line should beware of SaaSS.
