My point is that Kelley did not argue that what Bun does isn't really fuzzing. He wrote that the post's claim is a fabrication. But that claim is really specific, and to evaluate whether it is true it doesn't matter what Kelley's unstated definition of fuzzing is.

So an argument about definitions doesn't seem super valuable here.

The Fuzzilli PR was merged on Nov 20. The acquisition was announced on Dec 3. A big holiday was in the middle.

The teams no longer interacted after the acquisition, and in prior interactions the Bun team would've been correct in saying they weren't fuzzing.

So Jarred isn't wrong, and Andrew also isn't wrong.

Andrew was wrong. He stealth edited his post to hide it. https://news.ycombinator.com/item?id=48854921

I'm aware he edited it, but the original version isn't wrong, either. Just like Jarred's

> We fuzz Bun's runtime APIs 24/7 using Fuzzilli, the JavaScript engine fuzzer used by V8 & JavaScriptCore

isn't wrong, even though that was only being done for the last 5-6 months of Zig Bun, and not the previous 5 years when they were accruing all of their tech debt.

I'm having trouble understanding what you mean.

If I say, "I run 5 miles every day" and my old neighbor says, "I lived next door to him until 9 months ago, and he definitely doesn't run 5 miles a day," and then I show my GPS logs proving I've been running 5 miles a day for the last 9 months, I am correct and my ex-neighbor is incorrect.

If Sumner had said, "We've been fuzzing our code for years," then Kelley could justifiably say that's incorrect. But Sumner is saying that currently Bun fuzzes their code, which is true, so Kelley appears to be incorrect to claim it is a "fabrication."

That misses the mark here. Every other Kelley's claim has also been unsourced and not cited. I was able to guess that the integration might've simply been something which happened after they'd once not had it.

Given the lack of due diligence here, it seems Kelley's intentions weren't to be objective potrayal of truth but whatever was most damaging.
