You can find no trace of childish bickering in the language, tools, libraries, or documentation. I'm not sure why people doing silly things off in the distance would bias you against using Rust, the use of which would not involve those people ever.
While I think your statement is true, a few reasons:
1 - I will inevitably end up on some mailing list or forums when researching libraries, correct way to do things, etc, where such people interact.
2 - As 'governors' of the language, how can I trust them to make sound investments in the future? I don't want to just learn a language and tooling as a one off.
3 - I don't want to support organizations that act this way, even if the language were perfect.
1) This is an accurate complaint. By my estimation (on the official discord) they interact in such a way for an amortized three of the 1440 minutes in the day.
2) The language is pretty great. Further serious investment is going to be primarily in the third-party libraries department.
3) You need make no contributions, financial or otherwise. I am probably a net drain on the foundation's resources.
