Can there be open sourced subscriber based mobile apps?

Question

I myself prefer open sourced app for better transparency, but the question is can there be an open sourced subscription based mobile apps? I have not seen any major subscription based mobile app which is also open sourced. Is this achievable if so how?

https://github.com/bitwarden/mobile Would be one example. You can subscribe to premium features and all the stuff is open source.
