> Many site owners find that the titles they carefully craft almost all get rewritten. Yeah, I'm with Google on this one. I don't see many reasons why a site owner would spend extraordinary amounts of time to "carefully craft" page titles other than SEO and optimizing for clickbaitness. As a user, I'm fine with Google counteracting this.
I think that is the worst reason for them to rewrite titles. If they left the title as-is, then I would be able to see in the search results that it was a spammy site and ignore it. Instead Google is helping to launder their SEO and present it as a more legitimate site. If Google thinks a site is gaming their algorithms they should de-prioritize it, not rewrite it.
Forcing folks to trudge through inaccurate titles – or hoping people know the tells of a "spammy site" title – does not seem a better alternative.
