I’ve come to see it this way:

If a set of users are using a product only because it is built in X, that user base is most likely the early adopter audience for X and it dangerously masks whether that product has product-market fit or not.

So if a product markets itself as built in X, it is appealing to early adopters of X.

The long-tail of users on the other hand, care more about what painful problem the product is solving for them.

Now, some of the features of X might provide benefits to end users, but the long tail of users care more about those benefits they get rather than the fact that X provides those benefits, and that the product uses X.

An open source project also has to attract contributors. Rust is a competitive advantage in terms of appeal relative to languages such as C, C++, Java, empirically speaking.
