While some have been quick to criticize Microsoft for breaking backwards compatibility, others have applauded Redmond for making security such a high priority. Microsoft also points out that SP2 incompatibilities will most likely be limited to insecure applications:
"SP2 will break some applications because they are insecure," he says. "Security is important, and it is not just a Microsoft problem but a developer community problem. We all need to work together to create a more secure computing environment."If some applications rely on an insecure OS to function properly, perhaps breaking compatibility is a good thing.
