I get the appeal but I disagree
The strength of open source software is collaboration. That many people have tried it, read it, submitted fixes and had those fixes reviewed and accepted.
We've all seen LLMs spit out garbage bugs on the first few tries. I've written garbage bugs on my first try too. We all benefit from the review process.
I would rather have a battle tested base to start customizing from than having to stumble through the pitfalls of a buggy or insecure AI implementation.
