They’re different things. The comment you’re replying to is talking about different search engines. SearxNG is a metasearch engine - it combines results from multiple different search engines together.
Both are important. If you use SearXNG but only enable Google, it’s essentially just a proxy for Google and you miss out on most of the value of it. Some of the other search engines may have better results for some searches than Google does.
How would they even attempt to implement this? Will the US end up with a Great Firewall like China has? Even if Chinese models are delisted from Hugging Face (since Hugging Face is a US company and has to follow US law), they could just be hosted elsewhere.
