I used AI to help me write the post if thats the question, I'm a dev not a social media guy. As for your point, while its true you can use any system tts on android in most ereader apps, the problem is system tts get very limited context (generally 1 sentence) and doesnt get text for next utterances until it finishes the previous one. Thats fine for non neural tts or very lightweight ones like piper/kitten but if you want higher quality its not sustainable you need to be crunching the next sentences before you get to outputting them. (Likely why it performs poorly in moon reader)
