The source code is even hosted on GitHub which is owned by Microsoft.

I think you mean opnsense. I’m currently using openwrt with tailscale and adguard installed which is a pretty good option as well.

I get them from the Officially Translated Light Novels torrent from nyaa.si. If you don’t want to use the torrent then you can use the mega link in the torrent description to DDL novels.

You could also use a tempmail for the email https://adguard.com/en/adguard-temp-mail/overview.html

BTW do u know what the difference between the two PDFs they offer is?

This looks like a pretty fun show. I’m adding it to my plan to watch list. Thanks.
