Interesting experiment! I wasn't aware of it. I think it's difficult to extrapolate results, but I definitely have different takeaways than you.
1) The smiling aspect is explained (for me) by society pushing women to constantly smile, but not men. The amount we expect men and women to smile is different and when they violate those norms they're either a bitch (women for too little) or fake (men for too much).
I'm not sure how to interpret the tone aspect, and it's super interesting! It definitely flies in the face of multitudes of studies showing the reverse. I'm inclined to believe the studies which are really quite simple e.g. have people grade a short essay where the only difference between groups is the essay author's name.
