But it means sensitive files are constantly shared view public links, and you cant get access to the data to use in other apps. I wonder whether the negative sentiment created by hiding direct access to data and constantly trying to publish sensitive private data inside some kind of ad-link is more harmful than the attempt to get more users onto the platform via those links.
It will then download the file (if it's not locally available) and give you the option to share it directly via Messages, mail, Facebook, and all other usual stuff (with no link involved).
If you must own it yourself, you need to store it on your own servers.
