I haven’t used eOS myself, but in terms of privacy it is much better thsn stock Android. Just give it a try. In case you don’t lime it, you can switch back to Android.

Congratulations!

Do I understand correctly that you log in to your router over Tailscale and then from their you SSH into your server to uncrypt? Or can you access your server directly?

I set up Dropbear also for my server, but can only access it over local SSH. So I set up a Raspberry Pi which allows me to remotely unlock the server.

If you plan to buy a new laptop I would give my money to a (somewhat) ethical company which fully supports Linux:

NovaCustom

Framework

Starlabs

Nitrokey

Tuxedo

system76

Some of those even have core boot built in.
