I collected a example list of non-core law changes revoked by the Spanish government, to showcase the
vast differences on them and to display the irrationality behind the revocation, except
in two (pro-independentist)
cases.
Microsoft wanted to pitch its Surface RT as a competitor to the Apple iPad, though the
vast difference in sales of each
in the past few months has proved that clearly is not the
case.
As such, I don't think the ProCD
case applies
in my situation due to the qualitative
differences between licensing CD - ROMs with
vast amounts of information that has been compiled and which has value added search features added to it versus the «sale» of single copies of public domain sheet music (however, a library that creates and licenses for sale a CD - ROM with hundreds of individual pieces of public domain sheet music might be protected by the principles
in ProCD since a court might recognize and protect the library's investment of time and money
in creating the CD - ROM, but even
in that situation, if the library is not otherwise adding value - added information above and beyond the public domain content, it is not obvious that ProCD applies).
