I was excited to see Braxman on my podcast feed. He's great. But he does repackage things that other people have come up with and sell them as his own. His new phone relay service is borrowed from JMP.chat, which I have been using for 3 years as my primary phone service with 2 numbers and it offers a lot more for a lot less $. You can make calls and texts, with it too from your phone or your computer, and they have their own data SIMs in addition. Also, it is so easy to flash GrapheneOS or CalyxOS to a Pixel phone with the browser based USB flasher from their websites that anyone should be able to do it yourself. You don't need a Braxphone. Also SimpleLogin does email aliasing, and they are integrated with protonmail now.
