If you want a Free Software Foundation recommend distro, I would say Trisquel or PureOS (if you don’t need wi-fi). Or Linux Mint. Or Debian with Mate or Cinnamon desktop environment.

I will wait for Motorola.

In 2027, Motorola will realease a phone with GrapheneOS preinstalled. So no Google phone.

Mailo, 1€/20GB.

Open Source or Free > Source available > Closed source. Okay, I am glad that you allow me to see the program that I use. But if you don’t allow me to edit it to my needs or preferences, I won’t use your product.
