I owe @TheQuinbox an apology. When I posted my skepticism about Backtalk, I hadn't actually looked at the project — I didn't realize Quin was behind it. Having now gone through the repo, I'm genuinely impressed. The analytics are stripped out, network calls are all opt-in, the scripting engine has a proper permission model, and downloads are hash-verified. This is careful, disciplined engineering.
Unlike TalkForward or other efforts with questionable origins and no public repo to inspect, Backtalk is fully open source and built on a solid TalkBack fork with real security considerations baked in. It's refreshing to see Android screen reader development back in the hands of the community with this level of quality behind it.
I haven't been this excited about accessibility on Android since @nolan released Spiel. Looking forward to where this goes honestly. It's refreshing to see so many of the new stuff be opt-in and nothing shoved in your face unless you yourself enable it.
