Honestly the URL share is what I disliked the most. If the platforms shut down your channel, or if they go bust one day, there will be many dead links on dtube.

I have made a pull request to add an upload endpoint switcher on d.tube upload interface, which has already been merged and will be applied on the live website soon. This will reduce the load on the official servers as it allows users to choose a 3rd party endpoint to upload to, that may be faster and more reliable. Details here
