So a couple of things here:
1- The free version has all of the voices and also has all the core features including downloading and listening audio, i made sure to add the subscription feature in a way such that the extension is still usable for free users.
2- I have been spent hours (months even) on this project and kept it free. Due to my personal situation, I wanted to get support, i don't think that's a crime?
3- Any good developer is not afraid to ship things and then change them based off of user feedback, i knew there was going to be push back, but that doesn't mean i'll just stay quiet :)
4- If u want the entire extension that bad you can always just take a few weeks/months to code up a similar extension

Thanks for your review.
