Dropbox never worked on Linux for me. It was buggy and maxed out my CPU. They didn't even provide proper changelogs at the time.. not sure if they do now? Is their application open source? Rclone works with Google Drive just fine, and it is unlimited storage.

I had a major data-loss (recommended third-party element for KDE may have been responsible; was using free version), haven't used it since.

It's very similar to IMAP in the way a major data loss can be sync-ed. Would love to have "only mark remote deletions" (in both! with option to perform deletion locally on request), perhaps it's in there now, or part of the paid version.

I've been using the free tier of Dropbox on Linux (Arch Linux, Debian, Ubuntu) for years and I've never had an issue.
