A better comparison, if running your own reverse proxy was too complicated, would be to use something like Cloudflare Tunnels. However that’s still extra steps, they dont want you media streaming on their free plan, and you still have the issue of Jellyfin not being the most secure code that you really want to open up to the whole internet. That’s why a one size fits all answer is difficult.

Personally I think the idea of Recall is great if it works to help you and only you. The problem isn’t the idea, it’s the trust. If a reputable open source project or Linux distro made a feature like this I think it would be cool, because I know my privacy is going to be respected and the feature is designed solely to help me and nothing more. However, when MS suggests this I’m immediately cautious, skeptical, and concerned about how it could be used against me.
