Yeah, software support tends to be pretty bad for their devices, with few updates, and they are often bad with posting kernel source for their devices, so hard to get custom roms or flash alternative OS's on them too. But if you want a phone that has a battery that can last 3 days straight - they are indeed available for purchase
Unihertz and Oukitel both make "rugged" phone models with giant batteries - aimed at weekend campers with giant hands. And Fairphone and Volla both have phones that still allow for easy battery swapping.
Geddit also works well as an open source, no-account needed, Reddit browser - https://f-droid.org/packages/geddit.buzl.uk/
It's not completely over if folks help with porting more Fossil models over to Asteroid OS - https://asteroidos.org
This is the result of the default install of Fennec - it needs the user to install an extension to get ad and tracker blocking like you have
Here you can see that Fennec tried to "phone home" to Mozilla when I launched it
So that's the second test a browser needs to pass for me - no embedded tracker libraries. Fennec fails on that.
Embedded trackers Brave: 0 Fennec: 3
Not quite for me - Fennec (at least the build from F-droid) does not randomize fingerprint, AppManager and TrackerControl both show it has embedded trackers sending telemetry to Mozilla, and Fennec is not available on desktop. Librewolf is hardened Firefox on desktop, and is very good though, and has the trackers going back to Mozilla removed, but it does not randomize fingerprint.
I am guessing you are using uBlock Origin or similar with Fenec, as I just get "partial protection" in the EFF test unless that extension is installed.
Historically, more often than not, when a narcissistic megalomaniac is victim of a close call of targeted violence against them, rather than them becoming more empathetic with the sadly large swathe of humanity that also often faces targeted violence, they just double down on their own paranoia.
