Like the title of this thread asks, would you ever want to own your own video sharing site? I can imagine you would run into legal issues if you share copyright material on your website or let others do the same, not to mention it would be hard to compete against platforms like Youtube and Rumble. I wouldn't want to run a video sharing site for legal reasons, yeah I know DMCA ignored hosts exist but then you would also have to worry about the actual content your users are uploading on a moral level. Just would be too much of a headache, unless you only shared the platform with people you know in real life that you can trust.
