I work on TTS (created https://vo.codes) and my impression of the Mozilla project was that it was incredibly understaffed. Unrealistically so to ever lead to any kind of product or platform.
Maybe this new organization can accomplish the goal of easy and open trainable TTS. I'd really like to see it.
I would really love to see you get funding for developing an open platform for TTS that can offer commercial options that fuel growth. I really want to see your work scale. Easy TTS from custom data needs to be a thing.
Good job with the stuff you've built, and good luck!
