"What happened to Rust" is that it got a lot of coverage for being good, then a few people were annoying about how good it is, and now a large number of other people have become annoying in their complaints about how annoying the first group was. Meanwhile, Rust & its community remain unaffected; adoption continues to grow, and Rust now used in the kernel, Windows, Android, AWS infra, etc.

The problem you've encountered is that people are annoying. I'm afraid that's not specific to any one technology or community. Fortunately, annoying blog posts are easily ignored and would never stop a useful tool from being adopted anyway.

Rust is doing great.
