iCloud and Google storage plans are overpriced? I have always thought they are cheap storage plans. 50GB of iCloud costs $0.99 per month. 2TB costs $10 which is similar to other solutions such as Dropbox or OneDrive.
Yet someone could provide all of that for _everyone_ for literal 0-cost, and probably an actual ISP would provide at least some written guarantees on the redundancy of your data.
The business model of all these companies is to tie their software to their expensive storage.
