I'm on the same page with you that their AI stance is probably harmful for them -- but I think they wrote those as a reaction to the contributions from Bun and others. So your implied timeline is not entirely correct.

Nobody should feel insulted simply because a project decides to port its codebase to another language. It is a technical decision, not a personal attack.

Zig’s response has been a serious mistake. The TypeScript team ported the TypeScript compiler and language service from TypeScript to Go for TypeScript 7.0. Did anyone interpret that as the team insulting TypeScript itself? I certainly did not.
