Why screwed? MobileMe migrated to iCloud seemlessly and you had to pay nothing. Plus the service now is even better for free! I don't see that people get screwed.
"Even better"... more like different. MobileMe and iCloud have a fairly different feature set. If you used one of the things that was in MobileMe but not iCloud... too bad.
Right. And Apple provided paying MobileMe customers with 25GB of storage for free the first year. However, with the lack of an iDisk replacement, it's pretty hard to use up that space.
In other words, that what we did get, is pretty useless.
Sure but iDisk was little more than a generic WebDAV service, so you could easily replace it with a service from another provider with the money saved.
