Once upon a time, FOSS enthusiasts were so concerned about Microsoft, that they recommended everyone use GMail and Google Apps.
Today the same crowd hates Google, so they recommend $SERVICE instead...
As long as $SERVICE is a provider in the cloud, on somebody else's computer, I'm shaking my head.
Many of the things being recommended are even more proprietary and locked-down than Google's stuff is!
Fighting monopolies is good. But don't lie to yourself that this helps software freedom.
