> Saying "because they vibe coded we are dropping support for Bun" sounds political.

I disagree that this is a political stance. People based on their experiences have formed opinions on whether they trust that model of development or not. Bun having taking extreme measure of going 100% in within a week is itself extreme positioning from their side which will likely result in extreme reactions because depending on who you are and your experience you'd bet on the fact that it may or may not work out.
