By becoming the de facto entry point into the internet, Google's existence has spawned a horde of SEO spam sites that dilute and push down real content on the internet.

You only see it if you use Google, and you are always free to not use it. They may be evil etc but this logic is like "I can't stop punching myself".

Not remotely true, you see it every time you go to a SEO optimized site, however you get there.

And how, may I ask, do you end up on all those SEO optimized sites?

They don't push real content "down the internet" they push it down the google rankings.

And while Google search is not as great as it was, it remains a strong contender for the best way to find stuff on the internet.

I don't think the internet would be better off without it.

You can however make good arguments for Google News, "Instant Answers" in Search, and other products, taking (impressions) from the internet.(And Chrome, Chrome worries me.)

From experience, many people can truly not tell the difference.
