Because people will fill their iClouds. An important value proposition of iCloud is that customers pay for more space than they need. Time Machine grows to fill all available space.

They could sell a separate service for Time Machine backups. I'm not an Apple customers so I don't know if it makes sense, but they could make customers pay X times the last N days in the backup plus Y times a number M of snapshots in the past.
