Yes. We can point to the exact moment in time when Google turned to the dark side. It was on August 9, 2006, when Eric Schmidt, CEO of Google, addressed the Search Engine Strategies conference.[1] This was the moment that SEO, now officially endorsed by Google's CEO, became respectable. Until then, SEO was considered to be a branch of the spam industry. There were conferences such as the Web Search Spam Squashing Summit in 2005 on how to kill it.
There was/is whitehat SEO: properly creating links to relevant content within a site, using keywords that help bots find relevant content, traversing your own site to make sure there aren't dead zones with content that will never be found.
Google should have leaned into just this small segment of tooling and done much more of a ban hammer on the bad actors. They didn't and a bunch of people have left. I use DuckDuckGo mostly and sometimes Google but never by default. I don't even like DDG that much but it's good enough.
SEO sends the message that you have a content writer, and, thus, that you are a well established business (The content that is required to be produced is more nefarious than having hamster marketing guys spin in wheels, but the nature of the work is irrelevant to Google).
