Being only a 1:1 transfer is itself a problem when you need to send the file to more than one person. There are plenty of cases where you need to send a file to a small group like 4 or 5 people. Worse, this sometimes means you have restrictions like downloading the file one causes it to self destruct, which means if said person clicks the link on his phone then realizes his error and clicks the link on his computer the link will already be dead and you have to re-upload the file.
