I agree. I learned Ada in university (my professor was on the Ada committee) and used it for an embedded development course. The language was really good (many fewer foot guns than C or C++; clearly Ada was holistically designed), but I recall having issues with the tooling and the ecosystem, and the community was super defensive and hostile. If something wasn't working for your use case and the community didn't have a solution, then your use case was invalid. If you politely asked for help, you were incompetent or too lazy to figure it out on your own. This was a decade ago, so maybe things have changed since, but I can honestly understand why the language is niche. The type system and other intra-language features are very interesting but ultimately not the most important aspects of a programming language.
