I make it a point to never buy content if I can't download it. It's not even about sharing, it's about me owning what I buy and not renting it. You never know what might happen on the OF platform. I've heard Grithub is a free way to download. Personally, I purchased the lifetime subscription to YTSaver. It's clunky but it works. It's like its own web browser, you have to download either from messages or from the wall. It doesn't seem to work from the purchase section. I use it for all DRM protected content. You log in to your OF, go to the message and there's a download button right there. Only works on videos, not images. Hope this helps, hope you will share what you have. But even if you don't share, hope this helps you keep what you purchased.
