Counterpoint, I have seen sync issues on very popular large note, cloud-based solutions that use proprietary formats - Evernote comes to mind.

When you have tens of thousands of notes, it's hard to even know if at some point, the note has been suddenly changed, reverted, or modified in a way that you didn't even realize occurred.

With an open format, specifically a text based one like Markdown, I can sync all my notes to a git repository in a diffable manner that I can quickly review.
