For me it was watching my desktop folder. If I created a screenshot there would suddenly be a notification window asking me if I wanted to upload/share it via Dropbox. Contacted their support, you couldn't switch it off and they didn't understand why such notifications would annoy a user.

I stopped when I stopped being comfortable with them looking at my data. My sensibilities changed and software options had advanced to the point that the activation energy of switching to an E2EE solution had been surpassed. I use self-hosted nextcloud + wireguard + B2 encrypted backup. It's not perfect, it's more setup on each device (no longer a single auth away from the data), but it's well worth it to me.

There's a market here. Idk how big. Apple seems to think there's a market here too. If they offered larger sizes I might be tempted to go all in on Apple.

What does this mean in this context? I tried searching but couldn't find anything other than antivirus software sometimes quarantined files in their Dropbox folder which isn't really a Dropbox issue. Are Dropbox deleting files without notification?
