Well you're a robo ump extremist which is great but I bet the majority of fans, many of whom are casuals, are more or less ok with pitches like that being called balls. A majority of fans might not only accept that but are actually very in favor of pitches like that being called a ball.
Also, I think you might be surprised on how often you could end up disagreeing with robo umps. I'm 100% in favor of them but even robo umps make some interesting calls once in a while.
