I don't follow the drama. I only hear good things about Rust from the folks here at HN's, I personally never got interested in checking it out.
But I don't quite follow why it's so important to know what programming language was used to build your closed source binary terminal app. Cool you used Rust. Why should I care?
I use iTerm2 as my Terminal. Their homepage doesn't tell me which language it was written in, it has a nice page that highlights its features, and an extensive FAQ. In neither of these places language choices are highlighted. You only see that once you go into their gitlab, which is what I expect.
We started with Electron/Typescript and pivoted to Rust when it was clear that the performance was unfeasible for certain workloads (e.g. scrolling on 4k monitors).
If we already had a C++ terminal, I don't know that we would've rewritten in Rust. Starting from scratch, we were able to build an app and ship features in a good cadence.
We mention Rust in our marketing, because when talking about our features like blocks, code editor, visual menus, people automatically think "slow".
