There's advantages to saving documents to the cloud for backups.
Severely limiting that space by default and then preventing you from saving files when it runs out is horseshit. Half the computer problems I've fixed recently are all caused by OneDrive running out of space.
My sister wanted to know why her Sims saves were disappearing. Turns out OneDrive was full and the saves were being backed up to it. No space = no more saving apparently.
Because they know most people won't move to Linux. Most people will stick with whatever absolute garbage they know and will just be annoyed when things continue to degrade, but they won't leave.
No no you misunderstand-- It's primary storage. Your 1TB hard drive is merely a local cache for the $70 OneDrive plan that you for some reason haven't subscribed to yet, but don't worry, you'll get lots of reminders to.
Well if you fill up the space you pay for... What is OneDrive supposed to do if you try to add more files? How would it pick which ones to upload to the cloud and which ones not to? It would be pretty annoying if it just let you keep adding data locally but stopped uploading it imo.
It should stop uploading new files, and visibly notify the user that their cloud storage is full.
It should not start silently deleting your data after you save something, especially because OneDrive likes to "replace" your Documents folder as it were.
Imagine you work really hard on some important document, save it, and then OneDrive lovingly deletes it for you with no way to get it back because you ran out of cloud storage. Instead of, you know, just keeping it stored on your local storage and telling you it can't upload it?
Because that's what it does now. Just deletes your stuff. OneDrive loses you more files than it saves. Terrible product and always the first thing I uninstall.
