Here are two of Stallmans' writings addressing "Free" and "Cloud".

> Why Open Source misses the point of Free Software

> When we call software “free,” we mean that it respects the users' essential freedoms: the freedom to run it, to study and change it, and to redistribute copies with or without changes. This is a matter of freedom, not price, so think of “free speech,” not “free beer.”

> Who does that server really serve?

> On the Internet, proprietary software isn't the only way to lose your freedom. Service as a Software Substitute, or SaaSS, is another way to give someone else power over your computing.
