Nobody is actually disagreeing that Google is making a public CA, as it is in the body of the article, and is written by a Google employee. Rather niftich didn't read the article (and is common on HN) and wanted to say thee title wasn't accurate.
You're welcome to revert it back to the original title ('Google CA') as you mention.
> original title is the title of the article. Otherwise anyone could rewrite any title and call theirs the original.
Those sentences seem to contradict each other. Let's leave original title ('Google CA') and current title (whatever it is when you read this) as their existing meanings.
The ancestor post said 'Google CA' was misleading despite the article contents saying Google is making a CA. I criticised the action, which deserves criticism, and very specificaly did not criticise the user.
But I don't really want to expend any more energy here and suspect you don't either so let's leave this discussion.
