Not sure how far you wanna go. I know my way around mediawiki from the sysasmin side (installing, updating, installing extensions and themes, configuring weird features like ldap auth, …), the admin side (css, users and groups, templates and lua scripts), and some moderation (editing etiquette on wikipedia and a few other wikis, typical style guides, organization of pages and overview pages).

I’m quite busy lately, but you could ask me some questions via dm for example and I would be willing to do some small things.

This. Aegis does all of the points except offsite backups. And for good reason.
The Aegis app has no network permissions at all, which is obviously a massive boost for security and privacy. And besides, off-device backuping is a nightmare.

Syncing the Aegis backups made on change to some other server is better handled by a great dedicated app. Syncthing is the best such program (by far), though for the few files involved here nextcloud would work just as well.

I also find it to be very slow on many networks, and even in ideal conditions it might get 2MB/s when the phone has a 10MB/s connection.

For photos and predictable stuff I thus use syncthing, and the odd very large thing I send using scp with termux.

try {
    anal();
} catch (HIV) {
    loop {
        sleep(1000000000);
        if HIV.has_cure {break}
    }
}

It’s also completely fine under all international law.
Following copyright law is more like a trade agreement, so if you feel wronged enough as a nation it’s completely uncontroversial to suspend all or all international copyright law and deal with the consequences (mainly the us being very salty about it).

The EU contingency for a US attack on Greenland for example is among other steps to suspend all US copyrights recognition and starve the US service industry.
