I appreciate his contribution to growing the fediverse everyday with all these gifts.

I think it's a major loss considering the SEO garbage results you get nowadays. But the fault is on Reddit for doing this to themself, don't forget.

It's like email where each provider can talk to every other using the same protocol. In this case lemmy, kbin, and mastodon should be able to 'talk' to each other if they are in the federation (each instance or server has different rules about who they want to federate or 'talk' too) As you can see I am posting from a lemmy server to you on kbin.

As long as you don't share it with anyone I doubt it, but there is always a risk when you share content on the internet.

Jellyfin runs locally unless you manually expose it to the internet. Use a reputable VPN when you download content and you'll probably be fine.
