This is untrue, I use iOS Working Copy connected to my git repo which contains my Obsidian vault. It's also on on my android pixel phone and I have it on my windows machine. Everything syncs just fine using a private github repo.
Do you use end to end encryption? I don't want 3rd party companies to see my data.
Of course obsidian is not open source so I can't guarantee their e2e sync service doesn't sneakily send the data to their servers, but it's still less risky than having it easily available to the company employees.
