As I understand it, SearXNG is a decentralized and anonymized peer-to-peer network of search-engine scrapers. So you’re not self-hosting the search engines, you’re self-hosting a node in the network that scrapes real search engines. It’s basically search-piracy, except I don’t think they’ve managed or bothered to make it illegal yet, so, enjoy it as long as we can.

Because originally there wasn’t netting, and if the puck went where the netting is now, it would’ve been “out of play”.
The point of the netting is not to change how the game is played to be any different from how it was originally played, it’s just there to prevent spectators from needing facial reconstruction surgery when the puck goes out of play.
