What makes you think that the changes that are made in SaaS are always an improvement?

Sometimes that models permanently destroys something without providing users a recourse for going back. See: Warcraft II, or World of Warcraft

Rockstar removed around 180 cars from GTAonline recently... After literally years, just removed and partially put behind a paywall..

I think the SaaS model really depends on the Developer/Company. There are a lot of good and bed examples out there...
