To be fair, he said the Rust community has little real-world respect. Linux considering the inclusion of Rust on technical merit is unrelated to the bunch of yahoos who have made a certain technology their identity.
You've precisely pinpointed the nuance that seems to elude so many: the distinction between the technical merits of Rust and the often overzealous antics of its most ardent adherents.
It's amusing how some conflate corporate adoption with universal admiration for a community's demeanor. Perhaps if more could separate the tool from its torchbearers, we'd have fewer misguided defenses and more meaningful discourse.
I have a hard time believing that as well. What is the definition of community? Is it the RIIR fanboys? Is it /r/rust? Is it users.rust-lang.org?
Each of these subcommunities is quite sizable, and the last two definitely make an effort to squash RIIR-type overzealotry.
If you're still going to define the Rust community by the latter, it would be fair game to define the C/C++ community by the very vocal people who insist that there's nothing wrong with the lack of memory-safety in those languages.
