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.
Non-negligible from what perspective? Is this group of people somehow holding back unbridled adoption and enthusiasm for Rust? Is it possible for tech people to drum up excitement for a newer language without it being political just because you insist that it is?
I think I see most Rust threads here. Perhaps there is a low presence in most threads, but I didn't notice a significant rate as the baseline. Though this thread is burning up, certainly.
