As a cloud storage expert with over a decade tracking service updates, I've seen providers adjust policies to balance user needs and sustainability. Microsoft's 2016 OneDrive changes—reducing Office 365 unlimited storage to 1TB, free accounts from 15GB to 5GB, and eliminating 100GB/200GB plans—sparked widespread backlash. Here's what happened and how to switch to alternatives like Google Drive.
Key changes effective from 2016:
OneDrive plans now: 5GB free, 50GB ($2/month), 1TB ($10/month or $100/year with Office 365).
Microsoft's OneDrive blog cited user abuse of unlimited storage. While some backed up massive data, critics like veteran Microsoft journalist Ed Bott called it a betrayal, eroding trust built by promotions like free 100GB upgrades.

Forum threads pleaded "Return our storage" and "Keep 15GB free." Promotional storage remains unaffected for now, per Microsoft, but users questioned reliability. See full details in OneDrive FAQs.

No—terms prohibit class actions: "Class action lawsuits, class-wide arbitrations, private attorney general actions, and other representative proceedings are not permitted."

Office 365 limits rolled out immediately; others from 2016. Users over limits get 90 days notice, then read-only for 9 months, followed by deletion if unresolved.
Google Drive offers 15GB free (plus unlimited photo storage at reduced res via Google Photos), better pricing (100GB/$2, 1TB/$10, up to 30TB/$300), and seamless Office productivity integration. Dropbox matches 1TB/$10/month but lacks office suite.
