The examples given are spurious
The examples given (time shifting of broadcast works, for later private viewing, as a service) have nothing to do with 'cloud computing', except that the service just happens to use the internet and networked storage, somehow and somewhere. These particular examples have been thrashed out in the courts in various forms over the years, with various technologies 'in the dock'.
I would suggest that this 'study' is being used (badly) as a justification and a stepping stone to modification of copyright law and/or the control of copyright law, by people with vested interests in seeing this happen.
"Unless you modify copyright law, the bright and shiny future of cloud computing (and your cut of a multi-billion pound/euro industry will be threatened" Yeah, right.
