Why not build yourself from source?
I'm on iOS and I believe I'd have to pay Apple an annual fee for the privilege of building Signal myself and/or installing the compiled app. (Maybe I'd also have to buy a Mac or MacBook?) I also think I would have to reinstall my own build every few weeks and it wouldn't have access to my current chat history. But I've never tried. I'd love to learn about any misconceptions.
