Earlier quoted context omitted.
Google was/is also the largest sponsor of Mozilla. This doesn't stop Google from sabotaging Mozilla. 2 mln is probably Google's hourly profit. For that they get one of the biggest knowledge bases in the world. It's basically free as far as Google is concerned. The instant Google becomes confident they can supplant Wikipedia, they will.
Not sure why you're being downvoted; I completely agree with what you're saying (modulo questionable usage of "sponsor"). If Wikipedia were to try to charge for this use of their data, Google would likely make it a priority to drop the Wikipedia blurbs, either without replacement, or with data sourced elsewhere.
Then, after two or five years, let it fester then abandon it. Nobody gets promoted for keeping well oiled machines running.
