I think you underestimate how many people are in the "lite data hoarders" category. I don't consider myself a huge data hoarder. I have about 4 Terabytes. That's the totality of two decades of collecting music, video, pictures, ROMS, game ISOs, etc. It's enough that I can still fit it all on today's portable external hard-drives. And I don't think it's really much more than other people who might do amateur photography or videos and like to store their RAWs. However, it's more than is feasible for your standard iCloud/Google Drive/Dropbox plan can provide without significant burden.
At this point there's nothing really comparable out there to what Crashplan offers. Even the services like Amazon Glacier or Backblaze's B2 start becoming way more expensive once you pass the terabyte mark or so.

Yes, this is my point! It's expensive to store a terabyte in the cloud. There is currently no way around that. Crashplan was probably losing money on customers who had multiple TBs in the cloud.
If you had a lossless rip of a rare album that is not on iTunes, not on Amazon, not on Google Play Music, and cannot be found via torrents, wouldn't you want a backup of it in the cloud as well?
