Why I am leery of "The Cloud"

I am very reluctant to use web based applications. I avoid DRM'd content, and even with local applications, I shy away from proprietary file formats (I am pretty neutral on open-source but media/document formats and standards are another matter altogether). All of these create artificial roadblocks to the safety and security of my data.

How can I be certain the Vendor won't go out of business, or at the very least stop supporting the specific App? How can I be sure they are sufficiently protecting my data?

I can't.

I'm not feeling all that warm and fuzzy about "The Future is in the cloud"...
