I think the only point that matters is that having Anthropic owning a project which is written in a programming language where the community (or at least the leaders of it) have come out as openly hostile to AI generated code is a clear conflict of interest. I think Andrew Kelley might have been better to say just that and leave it - the comments about Bun's founders energy and motivations don't really add anything worth adding in my opinion.
Yeah, hard to imagine opposing AI absolutists settling their differences.
IMO all the technical arguments and attacks are post-rationalization; different orgs, different contexts, different goals.
I think Kelley saw this, but couldn't resist muddying his point. I give him a pass. The rant [0] is too much, but the addendum about moving on is healthy, and I'd rather the BDFL be too spicy than not spicy enough.
