It's targeting a very specific group of devs who like to follow trendy stuff..
To that group saying something is "made in rust" is equivalent to saying "it's modern, fast, secure, and made by an expert programmer not some plebe who can't keep up with the times"
> and made by an expert programmer
Quite the opposite. You have to be more of an expert programmer to achieve those same goals in C. Rust lowers the skill bar.
Anyways, I agree that the editorialization here is silly.
But also, I am unashamed that "in Rust" does increase my interest in a piece of software, for several of the reasons you mentioned.
