Have you addressed anywhere why you chose not to keep the copyleft license? It burns a lot of goodwill to use an AI for what many people will see as copyright laundering, and git has done just fine with the GPL, so it doesn’t seem like a blocker for adoption. What do you get from stripping the copyleft?
https://blog.gitbutler.com/series-a likely has a large part to play in it.
By which I mean, what do we imagine a16z thinks of the [L]GPL?
My brief experience in a startup exposed to them is that a16z seems willing to fund "infrastructure" projects more than most, but they did seem to have a ready set of answers on what "open source" means in that context.
(If someone can find me an a16z funded team that published copylefted code, I'll take this back.)
EDIT: Ok, i'll eat my hat, Gemini found me some counterexamples
