The website is a private undertaking which started literally a few days ago. It's not some official complete tracker.
The point was to show that big corps are dependent on Scala, often at their core.
Scala is likely not for everybody, but where you need to write safe high level code there is more or less no alternative, not even on the horizon. Scala is simply very likely where Rust will end up after the honeymoon, when people realize that feature rich, safety first languages aren't for the mass market, where mostly only the cost of initial development counts.
True, Scala (the language) offers lots of great functionality. And Scala 3 brought some important improvements.
But safety is not the only important aspect of a programming language. For me personally the community (libraries, tools, forums, blogs, etc) became much more important over the years, and I feel that Scala 3 really hurt the community angle.

That's also part of what I've said.
The point still being: Where you need a safe language there is no way around it, and Scala is still one of the very few options you have at all. Scala is in that regard indispensable.

I don't see that.
Everything relevant, besides Spark, is now on Scala 3, and this is already like that since a few years.
But I agree that Scala documentation / references / tutorials are to this very day lacking. This was and still is a real issue, and that's actually a very relevant one. I really hope this gets better with time.
The sub-optimal situation regarding docs does though not prevent people from starting new projects in Scala.
In fact Scala 3 is again ahead of the pack. It provides features not seen so far in any real world language and will almost certainly again pioneer the implementation of new language concepts in the large, as it did already in the past with its pragmatic approach to a OOP / FP fusion.
Just see for yourself what is currently happening:
