I think you know what I'm gonna say. No, it's not "lying". Stop using that word, or look up the definition already. Use a better word like "negligence".
I honestly thought you were going to agree that this would be a lie. I thought you were saying lies are about knowingly spreading a falsehood. Once someone at Google has verified that it's false, how does its continued spread not become a lie in the same way that it would be if that person wrote the untrue statement?
