Mostly because R is an overly complex language that doesn't have a large following.
This was started at Mozilla after they ousted their founder who went on to found Brave. The problem with garbage languages like this, and I do use the term garbage strongly, is that they are always raising the bar for programmers. Rust, C++, Java and the like are all absurdly complex and continually changing programming languages that make it difficult to hire really good programmers, especially when the colleges are programming people to become activists instead. Forty years ago they published source code in magazines and middle school kids could follow and program their own stuff in it. These days I have to interview a couple dozen shit programmers before I can find one who even understands basic algorithms.
