Hello
I decided to purchase a Teracube 2e from e-foundation about 6 months ago as I needed to escape the surveillance trackers and corporate control. I am a licensed psychotherapist and value privacy. It appears that e/OS/ is the most usable OS and similar to stock Android with a bit of IOS influence.
What I like is having access to TOR running in background continuously, always on vpn, and tracker blocker, all running with shelter in a work profile with only a few select apps. Most times I use an open wi-fi connection on Airplane mode. The T-cube performs exceedingly well with this version of e/os/.
