It isn't all of the objection, but there is a non-neglible amount of anti-woke people who find some weak technical reason to hate rust. It's silly but you'll be amazed in how often you see it line up when checking a random sampling of people who show up in rust threads just to make off topic complaints about rust.

EDIT: I hadn't fully gone through the comment section on this one yet and yikes it's worse about it than normal.
