...Unity made a blog post saying they were happy about you moving to Unreal, publishing they think it'd be a win-win, then outlining why they think so

I mean, that makes it all sound very polite and dispassionate, but Andrew's piece was anything but. I have no dog in this fight, I don't use Zig, Rust, Bun or Claude, and initially I thought the bun rewrite sounded like a terrible idea. I changed my mind after reading the piece about the migration - it was very interesting and the process was obviously quite thoughtful. Andrew's piece made me want to take a shower afterwards.
