Partially, the problem here is that the demand for classic search has been reduced quite a bit with LLM-based search finding wide usage amongst common people.

You could single out Google for it, as the DoJ and some other entities are doing, but even in that case someone else would take that place with the same dynamics, such as OpenAI or Perplexity.

Also, while building search is complex, it’s also not as unfathomable as it’s made out to be, see [1] where a ML engineer made a production-grade search engine in 2 months with their own ingest, indexing and storage infrastructure.
