Norton Backup cloud storage is overpriced

I just wanted to post some feedback here on the Norton Backup cloud storage fees:

(i.e about 100GB for $100/year)

These prices are not in line with what other vendors are offering for cloud storage.
e.g.
Microsoft has 1TB for about $100/year (includes MS Office subscription too).
iDrive has 1TB for about $45/year.
Dropbox offers 1TB for $99/year.
Amazon offers unlimited for $60/year

Why would I want to push my backups to Norton's cloud storage at the Norton rates? i.e. What is the product/service differentiator?
