The concept of using web-based programs like Google's Gmail is "worse  than stupidity", according to a leading advocate of free software.
Cloud computing  – where IT power is delivered over the internet as you need it, rather  than drawn from a desktop computer – has gained currency in recent  years. Large internet and technology companies including Google,  Microsoft and Amazon are pushing forward their plans to deliver  information and software over the net.
But Richard Stallman,  founder of the Free Software Foundation and creator of the computer  operating system GNU, said that cloud computing was simply a trap aimed  at forcing more people to buy into locked, proprietary systems that  would cost them more and more over time.
"It's stupidity. It's worse than stupidity: it's a marketing hype campaign," he told The Guardian.
"Somebody  is saying this is inevitable – and whenever you hear somebody saying  that, it's very likely to be a set of businesses campaigning to make it  true."
The 55-year-old New Yorker said that computer users should  be keen to keep their information in their own hands, rather than hand  it over to a third party.

The growing  number of people storing information on internet-accessible servers  rather than on their own machines, has become a core part of the rise of  Web 2.0 applications. Millions of people now upload personal data such  as emails, photographs and, increasingly, their work, to sites owned by  companies such as Google.
Computer manufacturer Dell recently even tried to trademark the term "cloud computing", although its application was refused.
But there has been growing concern that mainstream adoption of cloud computing could present a mixture of privacy and ownership issues, with users potentially being locked out of their own files.
Stallman, who is a staunch privacy advocate, advised users to stay local and stick with their own computers.
"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."
