If you really took the time to go through my posting history you'd see that I'm pretty evenhanded.
Of the big companies I use google where I can't avoid it, don't have a facebook account, there is one apple product in this house (a 2007 issue iMac which I keep running for testing purposes), my phone is an ancient (and indestructible) Nokia and I have an active twitter handle. That's about it.
So no, my M.O. is not exactly to just shit on anything Microsoft, it's just that Microsoft was - and is - worse than most. See: patents, intellectual ventures (you didn't really believe that MS didn't have a hand in that?), subversion of various legal proceedings against MS and even after being convicted using their lobbying power and business muscle to avoid their punishment.
That's probably a record for any tech company, feel free to list examples of worse behavior in the software world if you're aware of any.
