Having once been a paying Dropbox customer, I have been steadily moving away. Dropped down to the "free" tier and only keep it at all because of links others have to files I share. (And only manage it from Windows because of their lack of M1 version.)
Their attitude has consistently been appalling. Major increases in cost and trying to placate by increasing storage - which many of us simply do not want.
Partner uses Sync. I use OneDrive and iCloud. Sync seems now to have become too epensive for the smallest available paid-for tier.
But having problems with both. I simply cannot get OneDrive Finder extensions to work - so no choice about keeping items in cloud or on machine, etc. Gone round the uninstall/reboot/re-install merry-go-round countless times. And cannot see an easy way of sharing files anonymously - I don't want people to see my real name when I share a document. I should be able to do so anonymously. (In truth, I want to be able to choose whether they do, or do not, see my name.)
Yeah, this! It's been a few years now, since I worked for a business using DropBox, but we had a LOT of complaints about the way they ran things. The core product itself was pretty nice, but between big price increases with contract renewals, and an utter lack of attention to basic feature requests for the client? It just doesn't make good financial sense to stick with them.
EG. We always had issues with computers crawling to a halt because DropBox synced too much data to their local drive and filled up all the remaining free disk space. (Easy to do if someone shares a huge folder with you and you accept it.) All we asked for from them, for years, was a simple option in the client to refuse to sync when the drive was X% filled up. Pop up a notification to the user that they were too low on disk space and need to free some up to sync anything else. As far as I know, this STILL isn't in the product. Instead, they want to rely on the option to only sync file and folder placeholders instead of pulling down the content itself, until users click to open file(s). That's not always ideal for people.
