I have been asked multiple times on why I chose SQLite and not Turso. I've always responded people that I don't trust an open-source project once it's backed by a VC firm. I've moved away from Redis to Val-Key for same reason, and we have seen the Redis train-wreck in slow-mo. I hope at no point in future Turso ever ends up in that state, but chances are pretty high. At this point the "compatible with SQLite" has become a marketing term IMO, we all know how easy it is to break compatibility here or SQLite to break compatibility.
So then the follow-up question to that is:
How can we make sure that fundamental pieces of open source software that power the Internet can have funding, and that the people who write them can have comfortable lives working on the piece of software they love that so many people use?
I think you've described a real problem. But people turn to VC because there are few other ways to make funding happen.
I find it crazy that people would ask you in that direction. I would wonder why anyone would chose Turso over SQLite.
SQLite is some of the most battle tested software in the world. Turso seems like relatively new software that is still a bit experimental.
You do not want your databases to be new or trendy. You want your databases to be solid as a rock.
