I think your stance is more reasonable than the one in the article, TBH. If yt-dlp said something like "We're going to wait 6 months on the Rust rewrite", that would be reasonable. But instead it says something more like we think that Bun is vibe-coded, so we don't want to use it any more. That seems less reasonable.

It's not less reasonable. They don't have to promise giving Bun time in the future to evaluate. They might do it but they absolutely don't have to be responsible for doing it when the project made such dramatic shift.

They can do absolutely what they want with their project especially when its majority decision. There can't be no doubt about that.
