In general, there's a huge gap between who is influential in the day-to-day working of industry (even the tech industry) and public profiles. I can pretty much guarantee you that many senior executives of F500 corporations don't have Wikipedia articles. I could even point to founders of major US companies and people who figured prominently in popular books, especially from the pre-Web era, who don't have articles or who have pretty much a stub. Yet there are any number of articles about pop culture ephemera or someone who caught the attention of tech industry fandom at some point.
