The biggest problem with the open source version is that it's written in Go and there aren't that many people with both the skills and the time to maintain it, let alone expand it. It might be easier for a group of people to get together and build out a privacy centric open source project from scratch (something I'd be interested in).

It totally could!

I would suggest listening to https://fathom.transistor.fm/episodes/the-open-source-dilemm... too (published 10 days ago) as that'll give insight into our plans.
