How are you supposed to self-host a web crawler and indexer without getting a giant server bill?
Having this service at least slightly centralised makes sense ressource-wise - but assuming crawling and indexing is free is just foolish. I'd choose something like kagi but I guess many people will rather cheap out and go for the next free service not realising that that company has to make money another way to make up for the high cost of running a search engine
The problem is that it's just incredibly expensive to keep scanning and indexing the web over and over in a way that makes it possible to search within seconds.
And the problem with search engines is that you can't make the algorithm completely open source since that would make it too easy to manipulate the results with SEO which is exactly what's destroying google
