The concept you're describing is predatory pricing, but that doesn't appear to apply at all here. Market competition is alive and well in the cloud storage space.
I find that OneDrive tends to get hung up if it comes across a file that it can't read due to a lock. PyCharm for example will create a lock file, and it will cause OneDrive to halt all syncing until I close PyCharm and the lock file gets removed.
So DropBox, Box, and OneDrive are all dead?
