Watch Out! It's a Trap....
Go, RMS, go:"One reason you should not use web applications to do your computing is that you lose control," he said. "It's just as bad as using a proprietary program. Do your own computing on your own computer with your copy of a freedom-respecting program. If you use a proprietary program or somebody else's web server, you're defenceless. You're putty in the hands of whoever developed that software."
Mind you, I think it would be better if RMS came up with ways of taming clouds rather than just excoriating them (assuming you can excoriate a cloud, which seems unlikely.)
