Thank you for this, but I feel like you should make a profit and this is currently a missed opportunity to use web3 principles to do that.
Free and open software is a great ideal, but the reality is that people need money to live - and ads are the way to make that money on web2 platforms, which is why Google is in such a sad state. Why not do something similar to Brave? You can add tokenomics to the search engine and make money while keeping it 100% useable and open source.
