This was my thought too. I am considering doing the github blog but via Codeberg pages. While I would prefer to use the fediverse because most locations are potentially ephemeral unless a blogging option became popular they all run the risk.
I can't recommend unifi more. I moved into the ecosystem about 10 years ago with a USG and AP.
I run UCG with 3 WiFi APs at home and about 100+ devices, Inc 4 servers and 2 NAS.
Never have issues and it keeps up to date.
I have a separate WiFi for the guest house that is isolated and speed limited.
For a while I ran a controller to manage my home and my parent's farm network, they have a Starlink into Express with 2 U6LR and loco wireless bridge to cover 1KM of farmland with pretty impressive speed WiFi.
I typically take an express on holidays with me now which vpns home to keep our lan where we go, I just need hotel LAN for the WAN.
Agree - better safe to not risk it when crossing borders. Even if you don't have anything incriminating your identity can be stolen and used.
