Oh, Google are the champions of de-facto standards...as long as they are free, & can benefit Google. Give Eric a call, & ask him for the rights to use Google's search algorithm in your search engine...for free (de-facto standard & all). Yeah, good luck with that.
Google promote "open" standards & technology, just so they don't have to pay a licence fee, while gathering the user data they sell to their clients.
None of this is rocket science...& it is clearly hypocrisy.
And the products that actually generate Google profit are not open-source (ie. search). The only things that are is the stuff that they don't really give a shit about, but only acts as a trojan horse for their other revenue generating products. It's hilarious that people think that Google is pro-open source based on principle. They are not, and never have been. They use it for convenience when it suits their ends.
