2010's Google search code has been gamed many times over by sophisticated SEO schemes. So you can't bring it back "as it was". Best you can do is to restore its mission to "organize the world's information", but today's problems (e.g. AI slop) demand a new wave of technological innovation for them just to keep their head above water.

Also, it's funny you brought up politics, as if the current political regime is the last corrupt one we'll ever have. If you have the incentives for corruption in place, you will have more corruption. If you give Google to the government, it will use Google to support that corruption. The Trump era is a great time to be asking, "would I want the government to have even more control?", because there will be another Trump eventually.
