I'm a bit baffled by his hostile response. All I said is that I host and pay for my own server.
Nowhere did I claim that I host YouTube videos on that server, or that it is open to the public. I host that server for personal use, and for me and a few friends of mine. At most there is going to be two people connecting to it at once.

I have looked into hosting a peertube instance, but I've not really gotten around to figuring out how to set that all up.
