Technologically, I2P handles large data transfers much more efficiently than TOR. That makes I2P useful for torrenting large files like Linux ISOs.

K-9 mail… isn’t supported or being developed any more.

That’s not true. They make frequent-enough releases, they post monthly progress reports, and they are actually going to become Thunderbird’s Android version.

Having said that, I almost switched to FairEmail because K-9 lacked support for some sort of authentication measure (which I no longer need), but that wasn’t because K-9 stopped development.

Basically they don’t want NATO right on their doorstep.

NATO is not the anti-Russia club. They’re a defensive pact. Why would you be concerned about your neighbours agreeing to defend each other? Like a neighbourhood watch, perhaps. Maybe you’d be upset if you’re planning to do the thing they’re defending against. Which is all the more reason for those neighbours to band together.

At a glance, it looks like Aegis generates standard TOTP tokens, which means there’s a lot of software that can do the same thing, so you don’t need to emulate Aegis. I use pass-otp (an extension to pass), but that’s command-line-only, and a lot to deal with if you’re not already using pass. From a quick search, it looks like Keysmith and OTPClient are decent graphical alternatives. From another quick search, OTPClient is available in Ubuntu 23.10.

Edit: Re-reading your post, your issue is that you don’t like logging in on your phone, right? But Aegis just provides the code, you should be able to use the code from your phone to log in on your computer. TOTP codes are only affected by the secret values and the current time, so the code generated on your phone can be used on any device.
