Sure, I know people who spell it both ways, but in this case transliteration isn't an issue: you're talking about a public figure, the co-founder of Google, who's been in the US (and presumably spelling his name the same way) for 34 years.

This is just the case of a writer and/or editor being too lazy to look up the correct spelling.

Are you trying to ad-hominem the author? I don't understand the purpose of a comment like this, otherwise. Transliteration and spelling are distinct words and concepts. Frankly this is NBD to someone who is worth $NBdollars.
