The voices sound fine (some are worse than AWS, but some are indeed better). However, as a queer person, putting in sample texts like these[1] kinda put me off from your product no matter how good they are. IMO, that's absolutely uncalled for.
On a professional note, it's very immature( and silly even?) to use a product page to voice hostile idiosyncratic political opinions in general (regardless of whether I agree with them or not).
You're of course entitled to your opinions, and welcome to market your product however you want, though; I'm not trying to encroach on that.
