It's only a tiny minority that ruin media servers for everybody. Those tiny minority are not willing to self host because their content is usually against the media servers TOS or hosting companny TOS so they try to freeload off others. By requiring payment it will make sure it keeps those away as they will have to think hard and be forced to read the TOS before they pay to upload.

But yes. That will force that tiny minority to self host which is what they should be doing.
