>But who is "they"?
The person you're replying to.
>What does it mean to be "on the same side as Rust"?
There is a stated and auctioned stance the rust foundation poses, and they are saying they align with that. At this point if you can see their point the communication fault is yours.
>Being on a side suggests an unwillingness to part ways
No it doesn't.
>If Rust is a worthy rock in the political sphere for the moment
I have to assume their politics is more intimate to them than the maintainers of a programming language, and that they used it here because the conversation we are having is around rust.
> > But who is "they"?
You used "they" several times, so I took a certain usage to mean "Rust", and I was asking who specifically "Rust" entails. Who defines the "Rust beliefs"?
> > Being on a side suggests an unwillingness to part ways
"Suggests", as in, "it is likely implied that" (emphasis on "likely"), though I should've been more clear.

The primary topic is politics.

I find issue with the framing of "taking sides". I hear it and think of fragmentation for the sake of fragmentation. There is a distinct difference in saying "I side with Rust" and "I agree with Rust", the latter being reducible to "Rust believes [a belief]" and "I believe [the same belief]". The former can be used to mean the latter, but I choose to focus on the likely implication.
