Nobody else has made a better search engine
That's daft. Entering into the search market when Google did is a completely different animal than entering into the search market now. Google's one good idea--PageRank--was so much better than the other methods that it quickly dominated. From that it built a market valuation with very few rivals. During that time, the Internet grew exponentially, and the technology required to keep up has grown commensurately. Google may have started as a box under Sergei's desk, but you can't do that now. There's simply too much.
Even if you have a killer idea to revitalize Internet searching, good luck getting the kind of funding you would require. Your best bet is to bootstrap it, hope Google doesn't patent-troll you to death, and have getting bought out by Bing (or Google) as your exit strategy.
In any event, the quality of Google's primary product (that isn't slurping your personal data) isn't what it used to be. Trying to find something using Google is no longer the go-to. You have to use Google, Bing, DDG, whatever else you can find in order to get what you're looking for. Google's taken their dominant platform, and using political correctness as cover, to mold reality. Search terms for things Google doesn't like aren't suggested. Sites that Google determines are "untrustworthy" are deranked. And Google likes it that way.
If your instinctive reaction to anything Google touches isn't "how is this bad for my personal data and good for Google," you have to turn in your nerd card. Google is worse than '90s Microsoft on every metric, with the added insult that they think they're still an upstart with noble goals.
