I heart Wafrn, it’s the main way I interact with the micro-blog portion of the Fediverse, and its community has been overall great. One of my favorite parts is no character limit to posts, plus its great to be able to post & follow on Bluesky without needing a separate account or app there. Good stuff.

fwiw - Windscribe (based in Canada) has been working well for me, and they are fully open source - https://windscribe.com/

For those new to the process, the best general resource for instructions on how to unlock your phone’s bootloader and flash alternate AOSP ROM’s or non-Android OS’s is https://xdaforums.com/ Please note that not all carriers and oem’s allow you to unlock the bootloader though, so choose your device carefully for this.

You will also most likely need a PC (desktop or laptop) with adb & fastboot on it. These are apps used in the terminal, but you only need to copy and paste a few commands into them to use it.

If you have a Google Pixel then best option is Graphene - https://grapheneos.org/

For other devices you can use a “degoogled” Android ROM and get apps from the open source F-Droid app store - https://f-droid.org/ Some choices for this are: Lineage - https://lineageos.org/ crDroid - https://crdroid.net/ /e/os - https://e.foundation/e-os/ Iode - https://iode.tech/iodeos/

OR use a a true alternative mobile OS. Options for this are: Ubuntu Touch - https://www.ubuntu-touch.io/ Sailfish OS - https://sailfishos.org/ Mobian - https://mobian-project.org/ Postmarket OS - https://postmarketos.org/ Plasma Mobile - https://plasma-mobile.org/ Droidian - https://droidian.org/

You can also purchase devices with alternative OS’s already preinstalled from: Volla - https://volla.online/en/devices/ Jolla - https://jolla.com/ Fairphone - https://fairphone.com/ Murena - https://murena.com/ Furilabs - https://furilabs.com/ Brax - https://www.braxtech.net/
