i don't think Google has much to do w/ open source. their advertisement technology certainly isn't, is it? nor are the search crawlers technology. IBM, open source? i don't think you know what you are talking about. just because they released some Linux / GNU drivers for some of their platforms doesn't make then "open source" i'm afraid. IBM is foremost a HW compnay; HW, open source? same goes for HP, now owner of Palm... is your definition of open source company a company which (ab-)used open source, by any chance?
