Using a company's service is not the same as being completely owned by them. Kind of a dumb little "gotcha!" to try and feel clever over. What? should we make sure a company we like isn't using Windows before using their services, too? or Office? Outlook?
I can see how this rubs people, but rationally, what difference would it realy make if they run on Google's or Amazon's infrastructure instead?
Even 'own servers' would still be hosted in some major data center, connectivity served by the same corporate telcos.
