Do you mean why doesn’t he make a search engine? If so, that’s very silly.
First of all, if he is working on a search engine, why would he tell people while complaining about Google? That would just make it seem spammy.
Also even if he isn’t working on a search engine, how will the people who have the skills to make a good search engine know that there is a market for it unless people complain regardless of their own lack of skills?
If you make a small search engine as a prototype to develop better ranking and other things, that only costs time and mental energy. If you make a meta-search engine in the style of Searxng, that also only costs time and mental energy, and if you made it get all available result pages from it’s sources and then make sure they match the query and re-rank them, it’d probably be very powerful.
If you downloaded the entire Common Crawl (300 billion pages) so that you could index it, it would take up about 816 Terabytes, which using the cheapest surplus HDDs that I found would cost about $6000 for storage. If you used SSDs at standard market value instead, it would be about $40000.
It might cost 24 million if you wanted to serve thousands of queries per second right off the bat, but that would just be dumb. You could either build copies of your search engine and sell them as appliances, or you could make it available as an online service, and then just raise the subscription price until you have few enough customers not to use all your bandwidth. You could also charge per query. The Common Crawl is bigger than Bing, and possibly about the same size as Google, except that it includes archives of pages that don’t exist anymore. You can be damn sure you’d have customers.
