By engaging in the discussion threads (like this one, and the previous one, and the previous one before that, and the previous one before that, and the RFC before that...)
The Rust team doesn't talk much, but they do carefully read the discussions.
There have been so many discussion threads about this, continuing for months and months ad infinitum. There's been many opportunities in the past to discuss this.
The time to make your voice heard was months ago, when the discussions were happening. That time is not now. The discussions have already happened, and the decision has been made.
In addition, as I said, all of your suggestions have already been suggested many times, during the time of the discussions (which took place months ago).
When dealing with a large project (like Rust), there are processes that are followed. There are deadlines, timelines, and many many many people involved.
Making decisions is not easy, reversing decisions is not easy, and repeating the same arguments over and over again costs everybody a huge amount of time (and stress).
Rust is not a democracy. Things are not decided by popular vote. Rust is also not dictated by Reddit (who are a minority within the Rust community).
Adding more voices will not change anything. Repeating existing arguments will not change anything.
The only way to change things at this point is to present new arguments that have not been heard before (but that's unlikely, since essentially every possible argument has already been made).
