You, and searchengineland, are fixating on the word "widely." At the last company I worked at, my work email was in a single place - on the site of my company, on the contact page. According to the searchengineland examination of the word "widely" (which I'm not disagreeing with, and I think is a poor choice of words), it was not widely available.

Maybe "clearly" available is a better word? But fixating on the word "widely" is clearly a red herring, and is clearly not something that searchengineland is advancing as a reasonable criterion for a TOS violation, and is clearly being intentionally obtuse.
