No really. Microsoft? BSD TCP/IP stack for win95 maybe saved them but there was trumpet winsock and probably would have survived to writing their own on the next release.
Google doesn't get off the ground and has literally no products and no services without the GPL code that they fork, provide remote access to a process running their fork and contribute nothing back. Good end run around the spirit of the GPL there and that has made them a fortune (they have many fortunes, that's just one of them).
New projects from google? They're only open source if google really need them to be, like Go which would get nowhere if it wasn't and be very expensive for google to have to train all their engineers rather than pushing that cost back on their employees.
At least they don't go in for software patents, right? Oh, wait...
At least they have a motto of "Don't be evil" Which we pretty much all have personally but it's great a corporation backs it. Corporate restructurings happen, sure, oh wait, the motto is now gone. "Do the right thing" Well this is fine and google do it, for all values of right that equal "profitable to google and career enhancing for senior execs".
But this is great a robots.txt parser that's open source. Someone other than google could do something useful for the web with that like writing a validator, because google won't. Seemingly because it's not their definition of "do the right thing."
"Better than facebook, better than facebook, any criticism of google is by people who don't like google so invalid." Only with more words. Or none just one button. Go.
