The BSA is like the MPAA of the software industry, though MPAA is more stupid and dumb, but what BSA talks about is fair enough, companies should use legal software, I mean IT is a tool you use to do business so you pay for it. I mean IT is so ubiquitous now that it makes no sense for enterprises - small, medium or big to use pirated stuff. It's like would they not pay for electricity or phone and use an illegal connection - no right then why should they not pay for IT.
You know which is why Apple is a great choice for companies I mean an unlimited Leopard server edition costs $999, compare that with Windows Server 2003 and you enter into major licensing agreements. A big client of mine takes 3 months to get 1 server purchase request approved because they have to go back to Microsoft and ask for additional licenses. And if you calculate the Total Cost of a windows server where you calculate the time spent on getting the thing approved, build the server to corporate standards, install the security updates and anti virus products before you run it - man it is equivalent to buying a high end Mac Pro + Unlimited License.
Apple can really win in the enterprise if it can create a value proposition around this area.
